I mean.. it's okay. Not as good as the first one, that's a given.
I guess I 'll list what I DID enjoy first.. the animation is BEAUTIFUL! As a person who studies art, I'm very impressed with the design of the tree house and the backgrounds and colors! This is DreamWorks though so I was expecting good animation. My only complaint is that the animating style is a bit too.. expressive? It reminds me of modern SpongeBob episodes, which most find a bit too annoying. Overall, great animation nonetheless.
There is some funny moments, but mostly cringe jokes. Like when they ate all that food and went through that weird sugar rush? Or when Grug got all ape crazy and transformed into a typical caveman? Yeah, everyone would've liked if those scenes were cut out.
I adore Epe and Guy's relationship, and Dawn was a beautifully written as well. Major thank you for not making her try to steal Guy from Epe! Grug and Mr. Betterman's dynamic was a bit weird though, like him trying to seduce him in the man-cave (and no, I'm not saying that because Mr. Betterman's a male, it was just plain uncomfy no matter his gender) The Thunder Sisters was pretty wild and thrilling, they sorta came out of no where but whatever.
So, to sum this all up, it was.. good-ish. Suitable for kids I suppose, but it definitely doesn't add up to the heartfelt emotions in the original. I wish studios would drop trying to baby-proof movies nowadays, and maybe give movies an original and interesting storyline? But what was I expecting from a Croods sequel anyway.
