No I watched it twice.
It was james bond with memory loss meets a nice hot alien and a posse rides out to find the aliensThe hot alien kills the rest of the aliens after not 1 but 2 completely unbelieveable battles where 20 semi competent cowboys with 6 shooters somehow hold their own agains 30 or 40 fifteen foot tall, bullet proof aliens who can leap a 4 story building in one bound, rip a man in half with 1 hand (they have 4), and have far superior weaponry.
There were all kinds of douche alarms going off, trust me. It wasn't even interesting. (it was the extended version which may have been a factor)
