Nana's Everyday Life/YMMV

Crosses the Line Twice - Played straight at first, then horribly subverted as it quickly crosses the line again, and then veers at a non-euclidean angle to cross over an infinitude of lines that should not even exist. There is a term for people that are still laughing at the comic by the last few strips.
Crowning Moment of Heartwarming: Despite everything she's gone through, when Nana dies, she resurrects the dead kitten she spent her last few hours of life with and makes flowers bloom in the alley she died in. Doubles as a major Tear Jerker.
Darkness-Induced Audience Apathy: A common criticism by detractors.
High Octane Nightmare Fuel - Combined with Tear Jerker. Nana's world is the sort of existential nightmare where life has no meaning, there will never be a happy ending, and no matter how you hope, no matter what sort of happy ending you may beg for, there will only be pain. And cuteness, which only makes it worse.
Memetic Badass - Even people who have no soul cry at this!
The Woobie - The armless, legless woobie who lives in a box.
