Solo didn't deserve the backlash it got. It was a perfectly good star wars film
I don't know about "perfectly good", but it certainly wasn't the worst film ever as some made it out to be. It was ok, and when my kids and I watched it on Netflix we certainly never considered turning it off, etc. The thing is that with Star Wars or these Marvel movies, we want more than ok. We want something really cool that we want to see again or spend some time talking about after. This was like, "ok, not too bad, let's go outside and shoot some hoops".
This next Star Wars film needs to rekindle that spark somehow, and Marvel will need to somehow figure out how to set up the next ten years of their films after Endgame. I am curious to see how both franchises manage it.
