There are a thousand ways in which to resurrect Alex. Everything from the G'Lith, to an alien hybrid clone...but judging from their past performance, TPTB don't have the imagination necessary to come up with something like that, or the skill required to make it work if they do. Ergo, they still don't have my support.
If they do something like that...along with sucking Jesse into non-existence, I'll consider seeing the (as yet hypothetical) movie. If they don't, I'll spend the money at McDonalds. In fact I'd probably enjoy the toys in the Happy Meal more than I would the movie.

Added in Edit: Personally though, the only "Alex resurrection" scenario that works for me, is one where he never died, and the crap that we were subjected to in season three never came to pass. After what they put us through, TPTB deserve to choke down the nice big helping of crow that would go with that. Now
that I'd pay double price to see. Triple price.
