The problem wasn't that the ending could HAVE been better, but that the whole fucking series could have been better if MC wasn't such a massive faggot.

MC was a huge fucking faggot
MC a shit
The 10000 years stuff was a load of crap, but I actually liked the ambiguous final moment of the anime as opposed to the manga wrapup.
That said, the whole show was unraveling long before the final episode, so the chances of a satisfactory ending were always real low.
I didn't mind the MC, watching him lose his shit over all the stuff going on around him was fun in its own way.
The show was just poorly organised though. Lots of things could have been paced, written or explained better. The problems with the ending are just symptomatic of the problems with the show overall.
They should do a Hollywood adaptation of Mirai Nikki.
