Trailers for TV shows tend to be a lot, lot shorter than those for movies. I regret that when there's a show like The Strain, something that I just want to see as much of as I can as soon as I can. I'm fascinated by the look of this thing.
I hope the subsequent episodes can maintain the quality of the Guillermo Del Toro-directed pilot. I bet he's delivered a lot of guidance and recruited some very talented people at the very least.
