But I can see where 1 in 20 attacks doing maximum damage + bonus damage might be less than appealing to some. While the author of the post above forgot that a critical hit isn’t the same as rolling maximum damage because of the bonus damage (at least past level 1 when everyone should have a magic item of some kind) but I can see where even so it might not have a critical impact.
I’m not a fan of the Critical Hit charts, never really have been as they’re just too lethal for my tastes. And Fumbles on a 1 are just so Keystone Kops / slapstick comedy as to be ludicrous. Even a novice fighter I don’t think is going to fling his sword away 5% of his swings or stab himself in the leg or whatever.  It’s not very heroic for a Demi-god to drop his sword 1 out of 20 times he tries to hit something with it.
But this particular thought on the subject doesn’t seem too atrocious to me. I think in game play it’s going to tend to be more irritating for the players (DM’s roll a LOT more than players do) than enjoyable but with the right groups it might be a lot of fun.
The basis of this system is fairly simple, on a critical hit you roll a d20 and consult a chart and based on that chart result you apply an existing condition to the target (blind, dazed, weakened, slowed etc).
I’m recreating the chart portion below for my own perusual but I highly recommend you visit the site and peruse the items there.
