Some spoilers, beware. Honestly, I'm rarely a fan of time travel stories. They tend to be full of plot holes and half-baked logic. Since everything is theoretical, it seems like many writers just pull whatever rules they feel like out of a hat, and use it as a sort of deus ex machina. Very rarely is it used well in my opinion. Primer is one of the rare exceptions because it's well structured and thought out (maddeningly so), but overall I tend to skip such things. Also, it could be noted that Primer being about time travel could be considered a spoiler. I didn't know what it was about until it was actually revealed in the movie, and I was kind of happy having it that way.
