Really, Halloween is a nice little movie, but let's not get sentimental here: It's a definite product of its time and it helped father a genre that's showed us way crazier things. Halloween seems downright simple compared to what's happened in the nearly 30 years since.
Willco, we love the movie because we probably saw it for the first time when we were still lil tykes, and at the time it was the coolest shit ever. If such a simple script were being brought forward for the first time today, not only would it sound pretty tame, but it would sound kind of boring.
Halloween was the bombdizzle when it came out, but its descendents have raised the game. Some have done it in a brainy way (see Scream), some have gone for being sheer visceral experiences (oh, let's say Saw). Of course a remake is going to pack in some new tricks, especially with someone as nutty as Zombie behind it, and of course those ideas are influenced by the movies that have been made since Halloween changed the game.
