In whatever era, you'll get a few great movies, some really awful ones and a lot of mediocrity. That said, the ever increasing sequelitis and remake fever is a pain. It just means you have to dig a little deeper to find the good stuff, be it more esoteric fare like Black Swan or the summer films that rise above the usual laziness (Christopher Nolan's recent output, Pixar etc).

In the end the moral is don't listen to obsessives who complain about any adaptation (Thor got a pretty decent reception on the whole) and don't watch Transformers as it's crap on every level.
