4 has some interesting characters though, like the sabregirl and Louis. Even the villain had potential. But they combined too many weird and forgettable stuff in that movie lol. It was kind of meh, but still better than Ice Age 5 overall
I think the main problem is the franchisee writers keep making things bigger, which only makes them worse, honestly. Helping a human baby find its home, great. Saving the animals from a meltdown, believable but still ok. Journeying into Dinosaur land to save sid, getting stranger but nonetheless interesting. Battling pirates on ice floats while running away from drifting continents.... ok...
and then dumping magnetic crystals into a volcano to explode them into the sky and make a meteor veer away from earth and thus prevent hte death of everyone.... seriously? Just stop with these plots focused on the what rather than the who xD
Also, too many characters to make things work. All in all, "the main group" ended up being composed of two sloths, three mammoths, three weasels, and I believe two sabrecats. That's way too many characters to both animate and make an intertwined, coherent story around xD
