How hard is Adobe After Effects?

So as of recently I decided to try out Adobe After Effects. I've seen someone use it before and it doesn't seem terribly complicated, but I want to know how hard it is to use coming from someone else. Like, on a scale of 1 to 10.

Oh, also what would be a good way to get the program? I saw you can get the program for one year for $50, but a temporary pass seems sorta useless. I know buying the program costs over $500 so I thought about thepiratebay.org but if you can think of anything better (or at least more legal) then i'd prefer that.

Thanks!
