The ending was plainly bleh and flat to me, and I would have liked it had the writers put up the conclusion in an ambiguous note like, for example, the ending of Digimon Tamers.
Second, for this final battle they pulled out a unique scenario a la End of Evangelion to signal to the kids watching this show that Tagiru became the super-Star of the season surpassing Taiki
Also, what happened to the comrades and friends of the previous five heroes?
I mean they either appeared to provide a helping hand or made cameo appearances in the previous episode to help against the Quartzmon's invasion in the Xros War's universe but dissappeared like smoke in this final one.
I'm impressionable guy and had fun with the last episode, but one episode or even a finalé can redeem an entire series of redundant tropes and episodic content showing signs of not progressing towards a definite direction.
What piqued my interest were that Quartzmon in both design, appearance, and attack is one hell gross of a Digimon or digital entity. What it did to everyone by turning them to data and using their data as parts of its body was a doomsday nightmare for me to watch.
Quartzmon easily topples the D-Reaper and puts itself on par with Apocalymon as not only hideous, but a freaking God-like entity of pure destruction.
The other plot that was given conclusion and caught my attention was through Taiki finding out the identity of the clock-maker, old man.
Spoiler:
And, Taiki realizes and is hinted at that the clock-maker is, in fact, Baguramon in human form.
Has to be Baguramon, because if you recalled the end of the previous Xros War's season, Shoutmon X7 refused to absorb Baguramon's data, and instead hope that they'll meet again but with him being a nice guy next time around.
Also, when the camera's pans a close shot on the old man's eyes I got to see his right eye radiating a crimson-ruby glow, even if it was concealed by his glasses, and that eye glow is Baguramon's trademark feature.
Not to mention at one point his voice sounded exactly like Baguramon's.
Taiki's realization about Baguramon's true identity also sheds and solves another mystery left over from the previous season, also implying that Baguramon was and still is the maker of the Xros Loaders, after all.
Not a big surprise to cause a racket but puts me in peace finding out.
And, from the old man's last comment to the boys, it looks like that DarkKnightmon got revived, as well, and the old man is looking for him.
Given the following dialogue line, "I'm just your regular old clock store owner until! Until the day I run into my younger brother somewhere in the world."
I liked the implication from the old man's dialogue, that he being Baguramon may have turned into a nice guy or possibly an anti-hero of sorts to try saving world, if only to get a chance to do battle with Taiki and Shoutmon in the future, but that last line is a personal speculation.
I hope that I don't end up being the last person posting before the frenzy has quiet down.
