Pokemon GO is pretty boring and mindless. The gym battles are clunky and bordering on pointless too.
I've got a lot of gripes with the game, especially catching the same pokemon over and over and over and over and over again to evolve. The stardust and pokecandy mechanics seem really lame, but at least you cant flat out purchase them.
I do find some of the stops to be pretty entertaining though, a catholic church... some dudes grave came up today when my wife and I went on a hike. Annoyingly though none of our eggs hatched because we didnt have cell phone signal. But then again, theres just random garbage in the eggs anyway...
