This has already been said so many times, heh, but remakes are just consistently bad, appeal to the lowest common denominator and take all the attention away from the originals which are ten times better than any remake can ever hope to be.
The problem lie in if someone actually DOES a good job, the bad ones outnumber them and everyone throws the new stuff out the window. One done right is rare, but some actually improve vaguely on the concept. Look at Scooby-Doo... without the movies, I mean... the show has been remade and resurrected dozens of times, most times keeping with the concept, some changing it, but always striving to make it Fresh. Batman's another great example. He's had several solo series over the years and a few team up series as well. Sometimes remade, sometimes similar to another version.
But movies based off of kid's books just... they've had a history of not working. Shrek was the only one that overcame the handycap, but it changed the story completely other than an ogre a talking donkey and a princess ogre (which was handled COMPLETELY different in the book). It made 4 movies and 3 TV specials, and it almost had many many more films behind it... thank goodness they knew when to quit. Now it's hardly a favorite movie, but I do really really like it for what it was.
I barely or rarely dignify others. Polar Express, a cute little book, turned into an ugly special effects crapstravaganza, and Cloudy with a Chance of Meatballs turned into a gag, line, gag film with a TERRIBLE explanation of something that was best not explained.
The Cat in the Hat remake was funny (in my own opinion), but nobody liked it...
D'Snowth, you're the ONLY one that likes that movie. I read reviews that were so bad, they could have been seen as death threats. And I'm NOT kidding.
Now, i have to shamefully admit, I LIKED the Grinch movie... not so much for Jim Carrey (though I liked him at the time). They at least had a half hour special to go on with that one (I'm sure they ignored the special for the other 3 films)... plus, I have to admit, the Grinch's back story and intentions for stealing Christmas were at least good (where as the book/special he was just annoyed, in this version he felt the holiday celebrations were hypocritical for the citizens that outcast him).
Horton's a product of being a Blue Sky movie. Now, I've said this everytime I brought up Blue Sky... somehow they can make a good looking movie with a good plot... but it seems like they get halfway through the writing phase before they make the film. Like all their movies need one or two more rewrites to make the film complete. Horton was one of those movies. There were some good concepts in the film, Steve Carell, Carol Burrnet, and even the Narrator carried the film... but Jim?
I liked Horton, actually. Jim Carrey, who I absolutely hate as an actor, didnt even ruin it for me XD
I dunno why they even got him other than the name. Steve has a recognizable voice, Carol has a recognizable voice, Will Arnet and Amy Pohler... Jim? They could've got Matt Frewer for a fraction of the cost. However, I DID like the stylistic references to the Grinch (a character who couldn't be in the film, due to movie licensing reasons... he WAS in the Chuck Jones special) as this is Whoville... and I liked some of the concepts... but the "anime" thing where he was a ninja? There was no point in that (even though the 2-D animation looked BETTER than the CGI)... plus, Katie seems to be in the WRONG movie.
