Heaven's Lost Property

Note: Ecchi and fanservice is not a bad quality. Heaven's Lost Property (そらのおとしもの Sora no Otoshimono) is an 2009 anime series based on a 2006 manga illustrated by Suu Minazuki and published by Kadokawa Shoten. It was licensed by Funimation Entertainment.

Why It Rocks

 * 1) It has a great message of happiness and freedom which is the main theme of the series.
 * 2) Like High School DXD (DXD was created after this), even though it has ecchi and harem in it, it also has a large story arc that's interesting.
 * 3) Likable characters such as Tomoki, Sohara, Eishiro, Mikako, and Ikaros.
 * 4) Great English and Japanese voice acting.
 * 5) The concept of gynoid-like angels is well executed and very interesting.
 * 6) Tomoki, the protagonist, even though he's sometimes perverted, is very likable because he wants the Angeloids to be free from their slave-like mentality and have the freedom and happiness they should have.
 * 7) Very great and beautiful character designs and visuals.
 * 8) It uses more than 1 ending theme to fit the tone of the episodes which every episode uses a different ending theme.
 * 9) Very well done emotional and dramatic scenes to show that the series isn't only an Ecchi comedy.
 * 10) Great background music that fits the mood and tone of many scenes.
 * 11) Most episodes that begin with Eishiro are very funny as his "pretty" experiments fail as he tries to research the New World.

Bad Qualities

 * 1) Mikako can be very unlikable as she abuses Tomoki for little to no reason at all only when he's doing something very perverted.
 * 2) Some of the humor can get bland and generic at times.
 * 3) This show follows a lot of anime stereotypes and cliches.
