My first Horrorthon movie so far that I watched with another person! Kind of a lonely little contest we've got here, no?
I liked this one as much as the sequel, which I watched (out of order, obviously) last week. This probably would have been my clear favorite if I'd seen it back in 03, pre-I Am Legend or 28 Weeks, as I'd imagine that this all would have felt more "new" at the time. Had anyone else been doing this morlock-type hyperkinetic zombie thing before Doyle in '03? If not, it caught on quickly.
Anyway, if you haven't seen this one or the sequel yet, they're very worth checking out. Up there with Alien/Aliens in terms of the action/horror hybrid genre, I'd say, and a similarly strong pair.
** SPOILER BELOW **
I think one element that I might have missed out on by watching them out of order, was ever thinking that these were indeed the last people on earth. I mean, that's probably what most original viewers were thinking up to the point where the plane flies overhead, right? So that probably undermined some of the tension for me, and perhaps dulled some of the thematic "end of humanity" questioning as well.
