Time-travel is iffy for me. On the one hand, it can be used to tell a pretty interesting story. (Like how the first warp drive was made/tested), but on the other hand, it often ensures circular destinies. (Warp drive was only tested, and man uplifted, because the crew went back in time and made it happen.)

Those -really- bug me. I think the newest Star Trek did it in the most realistic way you could, though. Once time-travel happened, the original story that we all know and love has been thrown completely out the window (well, mostly. Somehow Kirk and the gang still end up on the enterprise) But Vulcan is no more. There's no undo, which is really cool. /thinking-too-much-about-this
