is it really that bad

Yep, it's pretty damn bad. The jumbled story doesn't add up, the acting is strictly hit or miss, the ugly cinematography gives the movie a foul washed-out look, the frantic nonstop pace proves to be more wearying than thrilling, and there's absolutely zero tension or creepy atmosphere. The grotty gore and subpar CGI effects don't help matters any as well.
