A 'bad game' used to just be something that you literally couldn't play, either through graphical glitches, a game engine overloading and dying on you, levels being unpolished etc. And while that's still completely applicable as a solid benchmark, there should always be allowances made for things like wasted potential and the increasingly money-grubbing way things seem to be going. Regardless of what causes you to feel like you're wasting your time with a product, it's about time certain titles and their respective developers were took to task for capitalising on the genuine love and passion anyone calling themselves a gamer will have for their beloved medium. Does that mean that downright broken games get a free pass? Oh hell no, they're all in here too - along with one particularly disgusting piece of software that essentially doubles as a piece of war propaganda - but it's worth pointing out that following what's been one of the worst years in the history of gaming and looking to another that's only peppered with titles worth investing in, the only way things are going to get better is if the right companies, franchises and methods of approach are appropriately criticised and remedied. So sit back but don't relax - it's about to get worse before it gets better.
