An hour!? Man, I never took that long. Maybe 5 minutes, possibly 10 minutes for a troublesome one. Mostly just a few minutes, though, and I got everything I could. I still agree that it was a pain in the arse, though, and I also agree that Mako levels were fun enough. I loved trying to get to the awkward little high up places that you needed to wrestle with the terrain in order to get to.
