The Force Awakens feels like a good film: good acting, solid directing, decent special effects, strong pacing with lots of actions scenes, etc. But it's ultimately an empty film, like a sugar rush that goes away. Look at ERA polls of favorite Star Wars films, TFA gets some of the fewest votes besides the first two prequels. It's just not a very memorable film because it's just a repeat of ANH instead of trying something new and fresh. It relies heavily on nostalgia/fan service such as seeing the Millennium Falcon, but when that feeling goes away, you are left without much. Essentially, it doomed the sequel trilogy by being a retread of the OT.
Rian Johnson had to take some drastic steps (Luke's arc, Snoke's death, etc.) to get the trilogy back on track, and he did an admirable job, but what did that matter when TROS simply undid his plot direction? That back and forth between JJ and Rian made one of the most incoherent trilogies ever. It was like the Halloween series when every new sequel just retcons all the past ones. And it all started with TFA and it's complete lack of originality, which was it's main problem no matter how good the film made you feel at first.
