Like most of Hollywood right now, if executives and producers stopped trying to make everything into generic action franchise movie, then it might be good. Tron was always a cult movie. Small loyal following who dragged countless friends family and living spouses to go sit for 2 hours to watch it.

If they would have kept it an ultra sci fi movie truly for the fans - it could have done moderately well. But they don't want moderately well, they want ultra blockbuster so tried to make it appeal to everyone. So it appeals instead to no one, and here we are. Another franchise on the fire.
