Well, the odd Star Trek films are always bad, if I remember my rules correctly. (and all I've seen of ST was the first season of TOS and Wrath of Khan)

I find it interesting that you brought up Koepp in this discussion, because he also wrote the lost world, war of the worlds, and the upcoming angels and demons. But I'm not going to see Transformers 2 because I don't really want to subject myself to another Bay film; unfortunately, Transformers to me represents the zeitgeist of our era, despite being hardly a good film.
