Finally watched the remake since it's out now on DVD, and ugh, what a dud. The effects looked great, and some of the action sequences were pretty inventive, but the movie just had no life to it whatsoever. And it had none of the mystery or sense of wonder of the original either.
Colin Farell can be fun to watch in some movies, but for some reason he just comes across incredibly dull playing the standard action hero. His Quaid didn't have even an ounce of the charisma or likeability that Arnold's had. And somehow Arnold was more convincing as the "normal, average Joe" type as well, which is even more bizarre.
I will say some of the new technology they came up with was pretty cool (like the palm phones and those magnetic restraint guns), but that's pretty much all the movie was-- a collection of gadgets and effects and action scenes.
