I picked up The Strain trillogy a while ago, by Guillermo Del Toro and some other guy, and while the premise is interesting, the first book is great, the second is pretty good, and the third is sort of like reading a fart.
I had high hopes and couldn't put it down for the first book and a half, then it got a little weird, and then I was just compelled to finish it because I started it, not that I really wanted to see what happened at the end.
I know, great sales pitch, right??
I started watching the show on FX and it was pretty entertaining, but missed a lot of the details and backstory that I thought was interesting in das books.
