I just got home from seeing it, and I thought it was enjoyable, even if it's in many ways a sort of remix of moments from 4-6. Originality is, thankfully, not required for a decent, entertaining bit of story.
The only parts I really didn't care for were when Darth Daddy Issues took off his helmet - put the mask back on, Nosferatu. The all-too-predictable death of Han, which started to be apparent from the moment he began bonding with New Jedi, and it became a certainty that he'd be killed while she looked on the moment we knew he was going with Finn to save her. And, finally, the awkward end scene with Luke - the iconic music used there will now forever be a love story between a boy and his long lost lightsabre.
