Basically which other characters in the movies do you think would have been interesting if they were the one with the premonition.

For me personally, I like the ideas of Rory, and Ian or Erin.

Rory to me would have been the most interesting in the 2nd one, I think his character was actually sympathic and I've mentioned that his scene with Kimberly before his death was in my opinion the best non death scene in the series. So, for me, a whole movie with Rory working on his demons, with Clear, and Thomas makes the 2nd movie a lot more interesting.

Ian being the cynic that he is, recieving the premonition would be interesting, the whole movie revolving around Ian and Erin might have been a unique dynamic. You can even do this same scenario, but give Erin the visions.
