Again, really my main problem with the movies is the "need" to change the characters' personalities so they'll appeal to today's audiences, which kind of ruins what made the characters so special to begin with, particular with the 80s/90s series, the cartoon was really well-written, and the characters had rather believable and relatable personalities for all kinds of kids and people. Granted, I haven't actually seen either the Squeakquel, or Chipwrecked, but based on what others have been saying about them, plus actually seeing the first one, it seems to me that: Dave isn't quite the stern yet loving father figure he was (more like a more insincere version of Ross Bagdasarian, Sr's Dave); Alvin and Theodore do seem to be about the same; Simon lost major points with fans over growling at the maid; Brittany isn't as sassy and diva-like as she used to be (which to me may not actually be a bad thing); Jeanette apparently just takes up space; no one's really said anything about Eleanor (though her "MY PRECIOUS! MY PRECIOUS!" moment is hilarious).
I don't think it was changing the personalities so much as not quite grasping the subtleties. Alvin was sort of Bart Simpson like (again, Simpsons writer), Simon didn't quite have the same level of nerdy shyness... but I think Theodore was pretty well written, especially in the second film (one of the only things good about it)... especially when he was starting to freak out about the family dynamic falling apart.
Dave was wrong, not because he was written wrong, but rather cast wrong. I did like the twist were he just got angry and abandoned them until he felt horribly guilty, but that's the only thing I'd think was written out of character. Jason just couldn't get that blend of stern and loving right, and he basically didn't like being in the film, and it showed. Meanwhile, in the Yogi Bear movie, they screwed up Ranger Smith and made him too lovable and almost EXACTLY like Dave should have been to the Chipmunks to Yogi.
HE should have been Dave. He had the right looks and the right tone that was completely wrong for the constantly angry, stick up his butt, but does care Ranger Smith.
But I wonder... were they even
trying for 1980's cartoon Alvin and the Chipmunks? The 1960's characters (except Alvin, of course) were subtly different. I'd say their personalities in the first movie are almost more akin to the 1960's series. The one where Dave wasn't quite as emotionally layered, but rather he YELLED quite a bit.
But I'll take slight change/not so fluent grasp of the characters over completely tossing them out and reinventing them to be something they're not.
The Garfield movie will always have a special place in my hatred for screwing up Jon Arbuckle. I can go into long pages about how Jon's supposed to be a loser you pitty until he does something so incredibly dumb or wacky, you laugh at him instead. Like he goes to the beach and
everything attacks him and he spends the entire time screaming. he's not mellow! He swings his head back and screams in horror quite a lot.

I'm starting to love Jon over Garfield. And they just turned him into a lovable lug.
Same thing with Inspector Gadget. Where was his inflated sense of ego, like he actually
does things correctly? And I get that you can't make Roshi a pervert in the US for some reason, but Chow Yun Fat
refused to be wacky or even resemble him. In Dudley Do-Right, only Alfred Molina actually knew what they were supposed to do.
But then there are rare times they get it perfect. Ape named Ape and George in George of the Jungle... Robin Williams in Popeye. He was more Popeye than himself in that movie. Too bad we didn't get a Dave who could get lost in the role. But that's my only major complaint.
