Saw Solo this afternoon. It was fine. I liked that droid. Didn't really like the guy playing Harrison. The Khaleesi was fine. Overall it wasn't awful but after the first 40 minutes I started to get bored. I am very shaken up at the moment and still managed to fall asleep for a few minutes during the whole 12 parsecs scene so I guess that means it wasn't very good. I'll give it another shot at home sometime. Maybe my opinion will change if I stay awake for the whole thing.
The Collider podcast talked just about the same thing you were talking about. But technically we are getting like 4 or 5 Marvel movies a year. Three from Disney and the others are from Fox and Sony.
I recall what they said and Lucasfilm was hoping to release two Star Wars films a year. It could happen within the next couple of years. It could work if it is done right. I personally think have one dedicated to the old storyline and the other movie would have nothing to do with the originals.
