What if the branch-offs were permanent and existed in tandem with the original timeline? So you could have this timeline and, say, a timeline where Obama didn't get elected for a second term. They'd both exist simultaneously, except maybe it's November 2006 in that timeline and today here. In order to "change" things in the other timeline, you'd have to make a third timeline.

In a sense, you would've simply added complexity to your own timeline.

It's an Amazon Prime movie, meaning I can watch it for "free."
