Getting some good titles, this is way better than my really terrible anime reviews. Now for Mahoromatic.

Mahoro is a combat android who served in the war against SAINT, an alien race bent on destroying humanity.
With the war over she is given options to how she would spend her remaining operational life. In a surprise decision and perhaps to rid the guilt of killing her commander, she becomes a maid for Suguru, her late commander's son.
What happens next is a funny comedy as Suguru deals with the fantastic scenario of having a combat android as a maid, friends who are too curious for their own good, another combat android and a sexually frustrated teacher; but the clock ticks down the remaining days of Mahoro's life along with the uneasy thought of SAINT returning.
That last bit is crucial, it's easy to write this off as a laugh worthy comedy filled with enough sex jokes to sink a battle ship, least we not forget the boob vacuum scene from season 2. But you see the clock tick down every episode and you get the sense that you'll be heading for quite a sad finale, and while it does happen and you expect it to happen you'll never be prepared for it, and that's quite a feat for an anime.
There isn't alot to dislike about Mahoromatic, although Shikijo is a bit much and the dub is somewhere between Love Hina bad and Haruhi Suzumiya bad (one dub actor is clearly carrying the anime)
Otherwise it's a solid comedy with some heartbreaking drama.
Final Verdict: A brilliant comedy with enough emotional investment to care for the characters and what ultimately happens to them. Worth the watch.
