Well from what i heard about the Obi-Wan Movie:
The movie will only play on Tatooine and he has to deal with a conflict between the Tusken and the local Farmers....
sounds very exciting...........
So hard pass on the Obi Wan Movie if that is really the plot.
They already
did that in Legends so I imagine a movie would have a bit more to it. But just because it's part of Star Wars doesn't mean it has to be all lasers and space combat. I'd quite like to see Disney try and broaden the pool rather like they've allowed Marvel to do with some of those movies, so a decent character-driven piece with Ewan McGregor could be good.
About the Boba Fett Movie
i don't know, i though it would be interesting to go into the Star Wars Underworld
but apparently they somewhat tried it in the Han Solo movie and it bombed, still have to watch that one.
Can't comment on the Solo side of things as I've not seen that yet (this afternoon!) but honestly the idea of a Boba Fett movie just holds no interest for me right now. The character has so little screen time or development in the OT and PT that I've no real investment in seeing more of him. Sure, there's a lot of room to play with to fill in his story (again!) between Geonosis and ESB but I don't see what the key would be to latch on.
If you go towards the early end of the timeline you've essentially got a child/teen space orphan wannabe bounty hunter, which might work as another "origin" type story, but that's following straight on from Rogue One where Jyn was orphaned and grew up with mercenary Saw Gerrera, Solo (I assume) will have some sort of background of Han being an orphan and growing up with smugglers or Wookiees or something. In the main ST you've got Rey as an orphan looking for her place in the world. Cross franchises and you've got Star Lord growing up with mercenaries over in the Marvelverse and Spiderman picking up Tony Stark as mentor.
On the other hand if you stick to the more familiar/iconic armour-wearing Fett at the other end of the timeline you've then got a hell of a lot of heavy lifting to set the scene at the start so everyone understands where we are and how we got there (whether or not they use a get-out-of-jail-free text crawl) and your hero is in full-body outfit. Alright that worked for Marvel with Iron Man and Deadpool, but both Tony Stark and Wade start out without the suit and are much more jocular and engaging characters (plus fourth-wall-breaking in Deadpool) than the monosyllabic Fett we've seen previously.
