Not doubt Will. I would go see that movie at least twice. I don't know Blabbs - Shatner seems quite comfortable with being parodied. He's one of the few people to Jump ON the Shark and keep riding - second only to the great Adam West.
@Abusive I think Blabby is probably referring to the studios that own the various characters. But I don't know if they're on any solid ground suing someone for writing a parody. That's fair use, no?
And for a small taste of what the movie might be like, I'd like to reference the Shatner on Shatner fight scene in Star Trek IV, when Kirk fights the David Bowie's shapeshifter wife.
True - didn't think about that. I just think of the Shat as his own entity rather than as a paid employee of studios. This could be his "Being John Malkovich".
