“Happy Birthday” (*1/2 out of four) was a crude, ridiculous comedy that is a birthday present left unwrapped. Two moronic friends embark on a road trip to Mexico for a birthday celebration but after a night of wild partying, they are imprisoned by two hookers who hold them hostage for a ransom. Or so it seems. Mash-up of “The Hangover” and “The Game” is sunk all the way by stupid characters and dumb writing. Steven Tyler from Aerosmith has a bit part as a psychedelic tent leader but he should dream on if he thinks this is going to lead to a side-career for him.
