In general: SO campy. SO gory. Jensen is SO pretty. SO cheesy. As Steve said last night before the movie rolled, the movie pretty much says "Fuck that" to any sort of nuance or subtlety. Guns pointing directly at the audience, blood and bone rushing toward the camera, pickaxes hurtling toward your face.
Conclusion: That boy's face and arms were made for the big screen boy howdy! Not an acting showcase in the least, but a good bunch of cheesy, gory fun, if that's your cup of tea.
