"The Last Action Hero" is a rare thing- an action comedy spoof that has difficulty remembering what it is supposed to be exactly. The action genre is certainly ripe for a mocking, what with the thousands of  "Die Hard" clones Hollywood has thrust upon the public. This  could have been the perfect spoof film- team "Die Hard" director  John McTiernan with The Terminator and let the jokes fly. But instead the  movie tries to be serious, then tries to make jokes about the genre, then  goes back to being serious again. The actors are making one kind of movie,  the directors are making another. It ends up a damn mess.
