I can relate. It takes a lot before I'm willing to leave the comfort of my 52" TV.
Eh, it isn't really the dearth of other entertainment one can find at home so much as 1) not a lot of new releases making me excited and 2) movie theaters, especially the larger ones, scare the fuck out of me and make me miss the 20th century. You know, back when moviegoing wasn't a multimedia advertising assault that spanned the entire range of ways people could blow their money or erode their brains/bodies.
Kind of going for the same thing as your second point, there.
