Our heroes are finally all together, and the dynamic is mirroring the original trilogy. The problem with the movie lies with the lack of creativity just like in The Force Awakens. They resuscitate without explanation Emperor Palpatine, and although it seems to be a good decision for the whole saga, its not a good decision for the trilogy alone.
Bring back Sheev, one would expect to see at least an appearance from Vader/Anakin in a ghost or flashback fashion.
The Rise of Skywalker is an energetic journey, nonetheless feels cartoonish. The third act is almost an Avengers Endgame copypaste.
