I had to sit through Ice Age: Collision Course. It was awful. I get it, it's a kids' movie. Talking animals. Cool. That works, until we get to what Blue Sky thinks of as comedy: Unfunny fart jokes, and generally forced humor. Also, how the heck do prehistoric animals know about hashtags when they don't exist in that time period? Ugh. At least the Scrat gags were pretty good. Other than that, it was a total cringe-fest.
I didn't like Minions, either. It was something that I wanted to see, but it didn't work out how I had hoped. Good idea, sub-par execution.
Frozen was one of those movies that I could enjoy once. Saw it the second time, and I hated it. It's one of the few Disney films I've seen that I dislike.
(Probably because of how over-hyped it is.)
And those are just my least favorites in the animation department.
