The tweets coming out are saying better than the prequels, but no.3 overall (behind Empire and A New Hope).
Patton Oswald who absolutely savaged the prequels also liked The Force Awakens apparently.
So overall it's looking pretty good I'd say. Don't expect anything life altering but it seems like JJ has made at least a solid Star Wars movie and one that maybe won't polarize the fanbase nearly as much as the last three films.
