Pure crack parody anime.
I loved it. It's fun, weird and keeps up the momentum until the end. I do, however, put this down as mixed feelings because you have to vibe with a Japanese sense of humor, be cool with bl/gl fanservice, and be prepared to not take it seriously at all. Also, skip Episode 5 because it was completely out of place and WILL kill the interest of most people. I have no idea what they were thinking there.
If you like the premise and your experience with anime isn't limited to dubbed versions of the most popular anime you find on Western TV, it's worth watching. Your viewing will benefit from a familiarity and appreciation for a particular sense of humor found in less Westernized anime.
Also, I've seen several people say the anime confused them and I'm confused at their confusion. The plot isn't complicated and there's nothing to read between the lines. So please don't let that put you off.
