@KaiserKitty from what i can tell, the more you like the other tron films, the more you'll like ares. i'm a huge fan of the other two with them being in my top 5 movies of all time. i love ares.
my brother and cousin were pretty meh about it, but they're meh about the other tron films too. the friend i saw it with today liked legacy but has never seen the original, and he thought it was pretty good. my dad and uncle like both the other films and they thought ares was really good.
