I liked Signs, it was odd, but I liked it.
Wahlberg's character was likable to me. I had teachers that actually talked to people like that, they were real and they forced you to think. I didn't like how awkward everyone acted towards eachother, but I was most impressed the moment Leguizzamo said "Only take my daughter's hand if you mean it". That, was good. "Be scientific douchbag" was cute.
I didn't like the copious amounts of graphic deaths (the lion thing made me laugh though) but I did like that it kind of made you think. The actual Happening is possible in this case, but so highly improbable its laughable. I was still going for the Lemmings theory that I had when I first saw the previews on TV.
