Sometimes, it falls in the trap of having to create more and more outrageous situations to keep the comedy flowing, but most of the time the characters and their relationships carry the show. It's like a otaku version of Working!, with one big difference: Working! had a normal main character, but such characters are nowhere in sight for this one!
We liked it. It's funny enough to be interesting, but watching this is far from life-changing -- if you're in the mood for light viewing and know enough about otaku culture to appreciate the puns, it's worth adding it somewhere in the middle of the to-watch list.
