Age of Ultron is a B-plus, and here's why.

Now, because this is me and I tend to dwell on the things that annoy me, I'll probably have more to say on the negative side of the balance sheet, so I want to establish right up front that as much as I dislike the problematic stuff, I consider AoU a pretty good movie overall. If the first Avengers was an A, this is a B-plus. It's good, okay? You'll have fun. It's just not without its problems, is all. And one or two (or three) of those problems are significant.
