There are always some questionable things in his movies, the fight scene on the drill comes to mind from his first Star Trek movie. But for the most part the 2 first Star Trek movies he did were okay, but I was never a Trekkie, just watched The Next Generations, and never cared much for the original stuff. I enjoyed the Force Awakens, still lots of questionable stuff, basically was A New Hope rewritten, but it at least felt like Star Wars. The last one was strange, but what company knows they are going to make a trilogy and doesn't have it all planned out from the beginning?
