Vague and sweeping spoilers below.
The Force Awakens is fully on a level with the original three films, as far as I remember them. These are four good scifi action movies. The new one is actually better in being much more inclusive of women and non-Europid people. It’s quite a loving re-visit to the original material.
My main complaints with the new one are that
- The tempo is too uniform and too high
- No time seems to pass between scenes, with the main characters never even having a change of clothes
- People need no training to operate star ships and military weaponry
- The story is a clear and intentional repeat of A New Hope
- It reintroduces the exact threat that the three original movies dealt with, obviating the entire struggle there. Cf. Sauron showing up and making trouble long after Morgoth got tossed into the Timeless Void.
