I thought Solo was pretty fun, but the reality is, this movie was only going to appeal to so many people. First of all, you can't replace Harrison Ford. You just can't. I got comfortable with Alden in the role, but knowing these Star Wars movies aren't a reboot of the universe, it never leaves the back of your mind that these aren't the people you grew up with in the original trilogies. I can understand that being a distraction with people.
Also, this is a case of too much too soon. People were let down with Last Jedi, and didn't want to hop into a new SW movie right away. There wasn't tons of hype on it until the last minute which probably showed that the studio didn't really believe in it as strongly either. SW isn't Marvel comics, which gets by on threading stories of larger than life types in a shared universe. With Star Wars, everyone with abilities only has one powerset, the force. These movies are a shared universe, but told in different timeframes and aren't leading up to a bigger goal.
Right now, if Star Wars is going to be successful on the big screen again, then the movies are going to need purpose. Not just pouring the same water into a new glass each time. And giving themselves some breathing room.
