Again, just my opinion, but an intriguing ending does not make a great movie. It’s why I find popular franchise entries like ESB and TWOK good... but ultimately overrated. They are decent, sometimes even stumbling into good or greatness. But they don’t work well on their own. TWOK is a revenge film with a sacrifice of a character that is heart-wrenching, but had Spock not died, would it be as well-regraded? Or would it just be a cheesy sequel to a TV episode? ESB Is probably a more apt example though. On its own, ESB is incomplete. Again, yes, the Vader/Anakin twist is amazing but the movie works better in hindsight when ROTJ is there and you know the rest of the story. It is incomplete otherwise. As an individual movie, viewed in a vacuum, it simply does not work having no real ending.
The same thing can be said about the second FB movie. The initial movie was just really the prologue. It introduced the characters and their relationships and while not perfect, was quite charming. The second film MIGHT be considered someday to be universally praised, at the moment, it’s been more or less panned by critics and fans. And in my opinion, for good reason. It is simply moving the chess pieces. I’m not sure if there was a change in plan for the number of FB films but the second entry really, to me, feels like too much and not enough at the same time. A big aspect of that is Queenie, who really was an integral part of the story and the group of heroes in the first film, who ultimately feels as though she’s shoved to the side, which brings her to the dark side (so to speak). It felt forced and completely unnatural based on the characters and their relationship in the first movie.
Honestly, in my mind, setting up the Nazi connection is absolutely fascinating, and probably the most intriguing part of the movie. But that was near the end and while sets a fascinating stage for further entries (if they really materialize) doesn’t excuse the meandering 2 hours that preceded that move. I mean, it is possible to build a standalone story at the same time not making the story feel incomplete.
Again, just my opinion.
