I think they missed a major twist here when they didn't have Jack go back into Slater 3 and save his son before the Ripper pulled him off the building. Seemed like that's where they were going, and I was surprised they didn't do it.
shareI agree. I was waiting for Slater to remain in the real world and marry Danny's mom, or if he was going back, then find a way to save his son.
shareIt's been a while since I've seen it, but doesn't Danny lose the ticket for most of the movie? That's why he can't go home. And I think the ticket is eventually destroyed. There's no chance to do it if I remember correctly.
shareSPOILERS:
They could have done it if they had wanted. At the end they had the other half of the ticket and Slater was dying from a gunshot, so they went back to the movie so that it would only be a flesh wound. Slater remained there, where he belonged, and Danny went back to the real world.
They could have gone instead to the previous Slater movie, and there save Slater's son. It would have made a more feel-good ending.
