I liked it, but not as much as I thought I would. I LOVE Simon Pegg and Nick Frost, and I like Seth Rogen. I thought for sure I would love this movie, but I was a tad dissapointed in it. Like it's been mentioned, it's not what i'm used to seeing from those guys and I was expecting for it to be.
That said, I did enjoy it, and everyone with me (not used to Pegg and Frost movies) loved it. I was also very tired and a little distracted. I would watch it again...but don't think i'd buy it.
