You have to like this type of game to enjoy it. The building system and survival system that is. As far as graphics go, Minecraft has these graphics on purpose! There is a very VERY large difference between old school pixilated graphics, and blurry graphics. Truly, "bad graphics" only occurs when the images are blurry or not well defined. The graphics in minecraft are quite well defined, they just have a retro appearance.
Some people may find it boring, but that is because they do not do anything. Try making a sheep cannon XD.
