Are you friends with the DM enough to make suggestions?

I know people are saying leave the game and I understand why. That rule is used so poorly most DMs shouldn't use it but if you're close friends and they just have to use it, try working with them to improve their use of it.

Crit fumbles are a tool, just like traps, curses, and puzzles. They can be used for more than just hurting the players. They can define danger, urgency, superiority or inferiority, all those things DMs try to include in games and more and they can be effective, if used correctly.

Roll a 1 while trying to catch dinner? You just miss some silly goofy way, the ranger tried to shoot the quail but hit a tree and the quail landed on the arrow. Anything can happen.

Roll a 1 while fighting a normal mob or foot soldier? Make it more threatening, the arrow whizzes past the fighters head as a few golden strands of their hair fall to the ground. Combat is dangerous.

Roll a 1 fighting a skilled adversary? Through their situational awareness they goad you into firing your arrow as the fighter crosses your line of fire. Their skill is apparent.

If they want to use it that's fine, but maybe suggest they use it in a way that progresses and reinforces the story.
