It's effective enough, but nothing special. There have been multiple action movies in 2015 alone with better action.

Abrams is waaaaaay way better at character, which makes this movie far more enjoyable in general than the prequels, but nothing in this approaches the quality of the action in the prequels except *maybe* the final light saber battle... but even then, that battle only really has weight due to character, not because it's especially brilliantly shot. That light saber battle, in terms of quality, obviously doesn't sniff either the Darth Maul light saber fight or the Yoda light saber fight, just off the top of my head.

Lucas was absolutely terrible at character and story, but his action, just from a technical perspective, is pretty top-notch. I did sort of miss that here-- Star Wars has been known for having some epic action, and this action was all mostly workmanlike (and there was that awful action sequence with the CGI octopi... ugh).
