Lifeforce is one of those movies that you really, really want to like, but it just isn't quite good enough to let you. It's a shame too, 'cause this flick had a lot of potential, and could've been an outstanding movie if the writing had been a little better and the acting not so lame. But in all fairness I have to say that the first 30 or 40 minutes were actually quite good. At first I really thought this was gonna turn out to be a cool movie, what with the voluptuous space vampiress and exploding zombies and such; but, sadly, after Space Girl escaped from the SRC building, everything slowed down to a snail's pace. There were a couple times during the middle of the movie where I kinda felt like turning it off and doing something else. The special effects were excellent, though... They get a 10. The first half hour of the movie gets an 8, and the rest gets a 4 or so.
