Legend
Minsc and Boo are like nails on a chalkboard for me. Maybe it's because I never got into the main Baldur's Gate series (Dark Alliance is another story, though). I think we could see him appear as cameo (and I think existing characters will mostly appear as such), but the idea of a whole movie staring Minsc would...not be my thing.
I think it's kinda like the more you see of him, the less chalkboard-y he is. BG1's characters really modelled the sort of PCs you might get in a slightly dysfunctional real TT RPG group pretty well. Maybe a little too well. And Minsc was clearly the joke-y guy's over-the-top character. Which can wear really thin, really fast. BG2 made him, well, still one-note but a bit funnier and more engaging (it did the same for all the characters to some degree).
But then when he's appeared in other things, it's basically just been to utter his catchphrase (which was such a thing they even reference it in Mass Effect 2/3), and just generally grin directly at the camera (metaphorically), as such characters do. So he gets very old, very fast, particularly with the perpetual "I'm in on the joke" smirk he's been drawn with more recently (even though in BG1/2 he has a "I'm too dim to get the joke but everyone is laughing so I smile!" smile instead).
