Tbf in that kind of a reboot they dont even need to be good actors, they just have to be grown up versions of the kid from the prior show. Which could be anything, so long as they are the same actual person that played the kid.

Wasnt Home Improvement what made Tim Allen famous, which was after he got busted for dealing cocaine or something? Itd almost be against the spirit of the original show if the guy who played Brad doesnt get his chance at the redemption arc

It would definitely be terrible
