This movie is truly a delight! It has an almost charming quality. The story line is interesting and well paced...no boring lulls and no gratuitous slashing and splattering of blood for pointless effect (a big pet peeve of mine). There's enough scientific rational to hold up the main premise, Vampirism as a viral infection (well, enough for me anyway ;) ). I found every single character to be interesting and entertaining. The setting is perfect; old & Gothic buildings, sort ethereal with lots of mist and fog when needed, as well as shots that included urban city streets, a hospital and lab, and of course one or two cemeteries. I enjoyed the timing and the way the film moved from one to the other, scary to funny and back to scary (great fun!). One of the best things about this movie is it's comic value, I think. Many laugh-out-loud moments (at least for me)...too many to recount here. There's also a nice light romantic subplot, but not too much (I'm not a big fan of a lot of all that mushy stuff--interferes with the movie). Another thing that I found really wonderful is the music, some really great pieces! Other movies that I consider to have great music choices are 'I Married an Axe Murderer' and 'Lost Boys' just to name the first two off the top of my head, but not because the music is similar, but because of what the music brings to the movie and how perfectly it helps mold the feelings and atmosphere of the scenes they're backing up. The music in Nightlife is like that: quirky, upbeat, and truly adds to the movie.
Overall, I simply love this movie and pull it out to watch whenever I want a smile. I just don't get tired of this great little flick.
