I forgot to put my own first impression in the OP so don't mind I put here. It takes lot of time to figure each series.
1. Fullmetal Alchemist (Will never watch)
Even they remake it again, there still no guarantee for me to watch it. Who cares about it anyway. The 2005 version failed with me and I rater smash my PC than watch it.
2. Shangri-La (May not watch it)
I just don't like its premise. Turning Japan into a tropical country is bad idea. You can do better than Gonzo.
3. K-ON (May watch it)
Well, I don't know how to begin with but KyoAni was rumored behind it. So far this might be a choice even I do not appreciate J-Pop songs that much.
4. Eden of the East (Reserved)
No screenshots available as I typing this. I bet this show just too 'heavy' for most casual anime fans like me. I also don't like using terrorists as bad guys because I afraid of some bad stereotypes might happen.
5. Guin Saga (May not watch it)
Its not I living in in 1990's, the last time I saw a poster like that, like a SNES game. Everything else doesn't hook me either.
6. Winter Sonata (Will never watch it)
Are Japanese crazy? Winter Sonata is the worst K-Drama I ever seen in my life and now some Japanese wants it anime-ted? After South Korea enraged with Hetalia and now they try to improve their relationship with that country by turning this crap into anime. I doubt it.
7. Sengoku BASARA (May watch it)
The first entry of video game adaptations cornucopia. Even though Devil May Cry was Capcom's failure but I hope this show will be quite decent to watch. Maybe I shouldn't put too many hope in it too.
8. Konnichi wa Anne (Will never watch it)
I don't to start anything bad about this show.
9. Senjou no Valkryia: Gallian Chronicle (May watch it)
Another video game adaptation. I like its premises even though I think this show will be better if its use proper WW2 setting instead. Let's hope it wouldn't suck.
10. Pandora Hearts (May not watch it)
A shouta boy, a tsundere girl and fujiyoshi young man. I start to have some bad feelings about this show right now. Another bad thing is XEBEC made this show, my least favorite anime studio. This also another shoujo show in this year which makes me stay away from it even further. I wish I was wrong on this one.
11. Saki (May not watch it)
Another loli jailbat show by GONZO after Strike Witches. I have feeling that this show may an Azumanga Daioh and Hikaru no Go ripoffs, just like its premises. Teaching kids to gamble huh?
12. Cross Game (Will never watch it)
Craps from 1980's should stay at 1980's, not 2009.
13. Queen Blade (May watch it)
A brutal version of Koihime Musou? I doubt it. The guilty pleasure of this season even though not the best one. Let's hope this show may not gain weight of its fanservices.
14. Hayate no Gotoku 2 (Will never watch it)
It may the best show in this season but unfortunately for I never seen the first one which this show will never get into my watch list, unless I get some access to the first one.
15. COBRA (Will never watch it)
I already have bad experience with Golgo 13 and I don't want it to happen again.
16. RAINBOW Nisha: Rokubo no Shichinin (Will never watch it)
By looking at its title I thought this will an anime adaptation of
Rainbow Warrior conspiracy but unfortunate I was wrong. Better left this one in the darkness alone.
17. Asuka Cryin' (May not watch it)
Another harem shows in this season. Even though it sounds promising but I don't want my list filled with too many harem shows, which makes me like a pervert towards casual female anime fans. Unless someone else prove this one a good show then I may give it a try.
18. Hatsuko Gentei (May not watch it)
Very much like Asuka Cryin' up there, I also let someone else give better impression before I do. Maybe I should choose between Asuka Cryin' and this show to see which one is better. The only weird thing is the only known male character in this show is a very large and intimidating fella. I just don't want to think about making him as a hero.
19. 07-Ghost (Will never watch it)
Even though its not a yaoi show but I'm pretty sure that this one will appeal yaoi fangirls alike. Maybe there is lack of 'true' shows like last year's Junjou Romantica
and such. I rather castrate myself than watching this show even for few minutes.
20. Tears to Tiara (May not watch it)
A Druaga clone? Not really but it has some similarities like its premises. I know I shouldn't compare these two but the similarities between them just uncanny. Let's hope it wasn't like that.
21. Hanasekeru Seishounen (Will never watch it)
The horror! THE HORROR!!! Yet another reverse harem show with some politics. Very much like Colorcloud Palace(I forgot its Japanese title), another show which I don't like. Even falling from 20 storey height is not as painful as watching such shows.
22. Shinkyoku Soukai: Polyphonica Crimson S (Will never watch it)
Another sequel of an anime that I never watch before. The probability that I watch this show is 0.0000000001%.
23. Kiniro no Corda ~second passo~ (Will never watch it)
ARGHHH!!! Another reverse harem. Kill me now if I insane enough to watch it.
24. Tayutama -Kiss on My Deity- (May not watch it)
AH! My Goddess ripoff? Even though that was one of my favorites but I really don't like to see human fall in love with a god/goddess/deity/whatever so better let someone give better impression of it first.
25. Basquash (Will nver watch it)
The only shounen in this season, unless you count the harem shows as 'shounen' too. I don't to fill too many shounen shows in list again.
26. Fight Ippasu Juuden-chan (Will never watch it)
Just looking at its promotional poster will give you a bad feeling. This show may turn into a ecchi mess. Even me, a casual male anime fan will stay away from it as far as possible.
27. Phantom : Requiem for the Phantom (May not watch it)
I'm tired with this Mafia stuff. That's all I can say for it right now unless someone prove me that I was wrong.
28. Natsu no Arashi (May watch it)
It is too early to say this one is either comedy or harem show. I think it may both at same time. I think I should try it.
29. Beybalde, Bakugan, Mainichi Kaa-san, Sugar Bunnies and Jewel Pets (Will never watch it)
(Un)fortunately I am too old for this shows. Better let kids decide about it.
Honestly this season kinda uninteresting to me and I hope Summer will be better.
