This is a lazy game, but what's wrong with lazy?

Something struck me the other day when looking through the comments for Cheshire's Cheese Nightmares on Steam Greenlight. Some people seemed to be implying that it was a lazy game.

That statement probably sums up the game quite well, I thought, but probably for different reasons. 

What's wrong with lazy?

We wouldn't call a musician lazy for recording a song with a single guitar and vocals. We wouldn't call an artist lazy for producing a sketch or a quick watercolour. So why is a video game lazy for not trying to be anything else other than a half-hour or so of easy relaxation? Lazy gameplay; relax and unwind.
