Okay, I'll step into the crossfire.
I tend to think that there are some movies that it might be nice to see redone. I've been wanting to see a remake of Navigator for a couple of years. The original was cheesy, anyway. How would Hollywood writers make it any more so? And it would be fascinating to see a CGI version of the ship's android.
So what if Hollywood remakes movies? It isn't as though this is something new . . . a fair number of the movies from the 90s were remakes of stuff from the 50s, 60s and 70s. And as for Hollywood not writing well-crafted, original screenplays in the past ten years:
Batman Begins, The Dark Knight, Fight Club, Children of Men, The Matrix, American Beauty, American History X, Saving Private Ryan, Amelie, WALL-E, The Pianist, Eternal Sunshine of the Spotless Mind, Requiem for a Dream, LA Confidential, Pan's Labyrinth, The Prestige, Inglourious Basterds, Up, Gran Torino, Sin City, Gladiator, Slumdog Millionaire, District 9.
Those are just off the top of my head, but you get the idea. It seems you're just not remembering what's good out there, and taking issue with the bad stuff. Avatar was actually a decent flick for what it was. Which was a retelling of Dances with Wolves. Big frakkin deal. How many times have they remade 7 Samurai in the past 50 years? And every single one was fantastic. The Magnificent 7 was even nominated for an Oscar!
I agree that The Neverending Story doesn't need to be remade, but if it does I will go see it. Just because it's a remake of something does NOT mean it automatically sucks. After all, a fair amount of Trek is just rehashing a lot of old episodes or characters. Trials and Tribble-ations, anyone? What about every Q episode of DS9 and Voyager? Or Lawaxana Troi's nightmarish-ly recurring role? Come on, all of it can't be absolutely original!
