For about ten dollars, you too can watch a hundred minutes of The Rock’s mad dog stare and all its variations. “Doom,” the new sci-fi movie from cinematographer-turned-director Andrzej Bartkowiak (“Cradle 2 the Grave”) is also part zombie, part slasher, and all big guns.

It’s based on a premise that’s become so trite that it (wisely) gave up trying to be anything else: A special forces unit of the space Marines is sent to contain a mysterious threat happening at a lab somewhere in space. The Rock and his twitching eyebrows play Sarge, the impossibly hardcore leader, and Karl Urban is John “Reaper” Grim, the haunted teammate who has a sister on that space station.

Sometimes you just have to roll with it, which is what I did for a while before the questions came: Why don’t they try the lights? How come no one cares when the dead guy disappears? Why is the doctor putting one of the captive zombies on an I.V. drip (he’s dead for goodness sakes!)?

I was rescued from this compulsive continuity checking by a series of scenes that looked like screenshots straight out of the video game this film was based on. I have to admit, I liked that part in a guilty pleasure sort of way, but it wasn’t enough to cover up the wandering story and its blatant need to blow things up.

On the other hand, explosions are what this movie does well - with a large repertoire of destruction and dismemberment. The acting was as good as it was going to get - with the characters dropping the f-bomb every few sentences, but the effects were spot on.
