They honestly should bring Boba back and have Temura Morrison voice him.

You say older like he’s some weather Clint Eastwood type, but it’s only been 5 years since the events of ROTJ.

In the novel Boba Fett escaped the Sarlaac pit so he's pretty much alive

The whole point of creating the mandalorians was that people loved Bobba Fett and he was supposedly dead, Lucas created Jango for the prequels to have a Bobba Fett in the past, but having a whole bunch of people that looked like Fett was just an excuse to have more characters that looked like him, and I'm just not a fan of that, I'd rather just have Bobba Fett as a bounty hunter that looked cool not because he was a mandalorian or because he stole a mandalorian armor but because that's just the way he looked, then they could have just "resurrected" him explaining that he escaped alive from the monster's belly or whatever if they really wanted to make a new movie or tv show.

I have the same problem with jedis, Luke and Kenobi looked like that in Episode IV because they lived in Tatooine, other people living there wore similar clothes and they were not jedis, it was just the kind of clothes people used in dessertic planets, once Luke became a jedi in ROTJ he used different clothes, however when people thought about jedis they remembered Obi Wan Kenobi with the hooded robe and the clothes he was wearing on the OT, so just because of that the jedis in the prequels also had to wear hooded robes and they just had to look like Obi Wan or Yoda when in the OT they looked like that because they were hiding and not because that's what jedis should look like.

This is a huge problem with Star Wars, everything is being constantly recycled, this happened with Lucas and it's being even much more obvious with Disney, they are just too afraid to try to do something new and only want to play it safe, this show is just Bobba Fett 2.0's adventures with Baby Yoda (another recycled character), maybe it's good (I've only seen the pilot), but I just can't get over the lack of originality, even the settings are just more dessert/ice planets, I understand that's what people are used to on Star Wars and it's cheaper to film in a place that looks like a dessert or to make it look like an icy place, but I just would like to see something new for a change.
