This is a good opportunity for me to bring up a game that I think falls right into what you are saying, a game which I will openly admit to being somewhat of a fanboy of: Deadly Premonition.
You see, Deadly Premonition's gameplay is akin to Resident Evil 4 shoved through a wood chipper. Aiming is slow, some maneuvers can be difficult to pull off, vehicles are a pain to drive, and York always does a little bit more or a little bit less than you want him to. If the game was really about the gameplay, I wouldn't like it.
There's a difference between a game that has bad gameplay and a game that has bad gameplay that isn't focused on gameplay. Hard Reset, for example, can be a real pain in the ass. It's gameplay centered, but the gameplay can be extremely frustrating. Your firing modes only switch when you don't want them to, and enemies are always placed in the most counter intuitive places, and it goes from being a challenge to being an exercise in smashing your head against the keyboard. Now, Deadly Premonition also has pretty frustrating gameplay, but it doesn't matter since it's about the story.
Deadly Premonition is filled with loveable, fun, colorful characters and a rich, deep, and interesting story. The thing that keeps you enduring the hordes of copypasted enemies and clunky movement is the hope for more of York's quirky dialogue, which is something the game is keen on delivering. Since the game lacks any form of fast travel, you can mentally go over clues and suspects while you drive your horribly controlled car.
TL;DR: If the game isn't focused on gameplay and the gameplay is bad, then the other qualities redeem it (if they're good)
