For me, it's got to be Call of Duty: Black Ops 3. Granted, this is not based on the quality of the multiplayer or the Zombie mode... it's 100% based on what was the flat-out dumbest campaign I've finished in a big budget 10 million selling title.
I wanted to post a thread like "What's the worst game you stuck it through and finished?" after fighting through what felt like the hundredth stupid dream sequence, the "twists", the zombies IN the campaign... it was melodramatic, dumb, overlong, boring, and just not not not a good game. I still finished it because I bought it and that's how I roll, but I hated doing it.
That said, I thought it would have been a *likable* game if it were a new IP. It would have been weird and unexpected and some people would have gravitated to that inane mechs and dreams and all those stupidly dull levels as it went on. But as a Call of Duty game, I just wanted to throw it at the wall.
