I think the problem with Solo is that it was released just a few months after The Last Jedi. People were possibly Star Wars fatigued by this point. (Just speculation)

Disney were releasing one film a year, Force Awakens (2015), Rogue One (2016) and The Last Jedi (2017). Each film was released in December of their respective years, including Rise of Skywalker which came out in 2019. Why release Solo in March?

Considering the drastic reshoots and production issues to get the film done, I would've thought aligning the film to December would've of given production more time to breathe. PS I would love to see more of the footage shot by Lord & Miller, but just like the Rogue One reshoots, that's locked in the Disney vault, never to be seen.

PS - I really like Solo as a movie. It's a lot of fun and I own it on 4K!
