I never review movies but I needed to for "shed of the dead": I agree with 2 of the reviewers, there is something wrong with most reviews. This movie is poorly written, the cast is meh, it's just vulgar at times, not funny (I mean not once), not clever. Someone wrote "it's not shaun of the dead" and well, it's clearly not; yet that flick gets about the same rating on average... yeah right 'cause that's believable.
Do yourself a favor and watch something else, anything else really unless you need to watch every zombie movie out there.
