I still like the majority of remakes that I liked as a kid. I wonder if the majority of people still like the remakes they liked when they were too young to know better (for nostalgia sake at least) or if more people dislike the remakes they liked as kids (I know The Nostalgia Critic tends to hate them, ignoring any nostalgia value).
I saw The Little Rascals movie before I saw any of the Our Gang shorts (and I think I didn't see any until at least two years later). In fact I saw many animated adaptations (Bill and Ted's Excellent Adventure, The Real Ghostbusters, Beetlejuice, James Bond Jr., Attack of the Killer Tomatoes, etc.) before I saw or even knew about the source material. For a long time I thought that the animated shows came first and the live-action movies were based on the TV shows.
I thought The Flintstones was great and its sequel almost as good (can't think of anything I don't like about it, but it doesn't feel as good as the first). I really like the live-action How the Grinch Stole Christmas, but feel The Cat in the Hat is real mediocre. I was turned off by the fact that in Inspector Gadget Dr. Claw's face was shown for the majority of the movies (and promos), especially with him looking so human. Heck, that had too many differences from the cartoon, the chief never got blown up with any self-destructing messages, it contained some main characters (Gadgets love interest, the talking car), and until I saw the movie I thought Penny and Brain would be absent (seems they didn't appear in promos at all). Bewitched wasn't too bad, but then again, it's about the making of a new Bewitched series.
There's also film adaptations I've seen but haven't seen much of the shows they are based on. George of the Jungle was good, while I liked My Favorite Martian a lot better when I first saw it, and I don't know what to make of Lost in Space. All of these properties I have rarely seen the originals.
I have also seen a number of more recent remakes. I saw Underdog but never really wanted to and feel it's as bad as I expected (in fact it's also as forgettable as I expected). I saw the first two Chipmunks movies and feel they're not that bad. I even liked The Lorax.
One adaptation that I liked a lot better as a child but a lot less as an adult but still like a little (a very little) is the Super Mario Bros. movie. But even when it came out I had a problem with Bowser being a human for most of the film and might have been bothered by the Goombas being big lizards, and I was confused by the princess being named Daisy instead of Toadstool (I had not played the Super Mario Land games yet, so was not familiar with her). All of the other differences that are too different from the games I wasn't bothered by until I was older.
I am mixed about the Rocky and Bullwinkle movies. I really like the Boris and Natasha movie, which many fans seem to hate (if they are aware of it). I recently saw the film again after 15 years, and there are problems. There's a lot of funny material, but some of the humor doesn't come out too good, and at times the movie seems to be a more generic crime drama. The actors are good in their roles (even if they seem to bring in too much personality to the characters), but neither of them have the right hair: Boris has a full head of hair while Natasha's hair is too short (and yet the film makes a big deal about her hair, not sure if that was intentional or not). I didn't like the Dudley Do-Right film too much, but Dudley Do-Right is not my favorite segment of the show. And Rocky and Bullwinkle was both good and disappointing. I wish it would have included more characters from the show (Mr. Peabody and Sherman, Dudley Do-Right, Captain Peachfuzz), wish Boris and Natasha would have been in more of the film (seems Fearless Leader actually gets more screen time), and Natasha's hair is not right here, either.
I also consider the Garfield movies to be guilty pleasures. Garfield the character is fine, but he shouldn't move his lips when he talks, and the other animals should have been cgi as well. Or they could have used a real fat orange cat and had no lip movements (they wouldn't have had to worry about that effect). Jon is portrayed more as an average guy than the loser he is on the show, and Liz seems to be an average hottie. I admit, though, I hadn't been reading the comics as much and had no idea that Jon and Liz had become a couple (after many years of her rejecting Jon and giving sarcastic comments, with only occasional moments where she does date him, some of which actually do seem genuine).
