pros
+ highly funny if you approach it from the right angle
+ mystery, action, religion, clichés, comedy, ecchi
+ fairly good animation
cons
- highly perverted with some childish jokes (hey? this ain't for kids)
- storyline stays in the dark, a lot of things are still unexplained
- far from original

conclusion: perverted as heck. not like the summary would leave any doubts about that (not like seikon no qwaser, where you expect mostly badass action and get mostly breasts shoved in your face), but it might be a little hard to get into. if you expect the amount of ecchi though, this is fairly entertaining in its own right. pretty clichéd in parts, and a lot of things stay in the dark plot-wise, but there's always the second season. works with a mixture of a lot of themes (see above), relatively good animation, and varied comedy. (the latter may be a point of criticism as some of the comedy is pretty retarded and would rather fit a kid's sense of humour... in an ecchi anime. -.-). but anyway, for those who expect the perversion, this is probably one of the better around.

peace. (show less)

as the title of my review says, this anime was decent. but the concepts in it were far from original.
alot of the overall themes of ikaros, and nymph were taken (in my opinion) from DEARS, now im not rightly sure of the publication date of either and i dont care enough to look, just saying there are very definate similarities.
now thats not to say they are bad, on the contrary, i quite enjoyed both series, (im probably a bit F*ed in the head thoug :P ) concepts are about all the two shows share though, the stories couldnt be more diffrent.
where DEARS, kinda pandes to the slice of life, sora no otoshi, takes a little bit of mystery, action, religion, anime steryotype comedy, some chibi (cuz it can), and a whole metric ton or two of ecchi. and mixes it all in a big ol cauldron. and what we get, is sora no otoshimono. i wont claim it to be ground breaking, but its worth the watch.
