Like the game, my movie would have 4 new vault hunters, with a supporting cast of returning characters. Perhaps each would have found a respective vault which lead to a piece of a key which they all need to work together to combine and open the mega vault.
Lean a little less into humor, add a touch of seriousness, not cast little funny Kevin to play strong serious Roland.
And obviously set it up for a sequel and a prequel.
Or maybe, now hear me out, make powerful pos pay for their own lawsuits.
