I have seen that...and I think its a mistake, following the prior error of slapping Solo's release in the middle of a whole bunch of other much-anticipated films. With the overlap fandom between SW and Marvel, they were foolish to think Solo would do well released so closely to Infinity Wars. Disney needs to think about its film fans way more - we had Infinity Wars, Deadpool 2, Solo, and Incredibles 2 all released in a clump. I personally don't know anyone who wants to go to the movies that often, and of the 4 films, Solo would fall to the bottom of my list simply because of the anticipation of Infinity and Deadpool and that my kids want to see Incredibles. As a stand-alone, it was too easy to back-burner Solo due to its timing.
Now, had Solo been released at the end of August (when there isn't SW/Marvel/Disney flick saturation), I think they would have seen much better returns. They need to learn how not to compete against themselves when timing releases.
