I watched DVD1 of Lala... I quite enjoyed what I saw. Still need to watch DVD2 (it's only been on my shelf for nearly 2 years ~_~) and order DVD3-6 (with Bandai's recent price reduction of these disks, there is
no reason for me to not have them...).
If you enjoy shows of the mahou shoujo (magical girl) sort, I'd suggest you try this one out. Heck, with the MSRP of the 6 DVDs being 9.95 (or thereabouts) USD, you can't really go wrong.
