The problem I have with Watamote is that not only does it go the "let's all laugh at how miserably pathetic this person's life is" style of comedy, but it also implies she has a near-zero chance of breaking out of her routine, something she desperately wants to do, which, even though it's all fictional, is still somewhat uncomfortable for me to think about.
A lifetime is a long long time. She would eventually mature enough and break out of it or at the very least reach an improved situation. A lot of people who think that way are very young.
