I really liked this show. The humor is very lowbrow and some of the plots get really dirty. It is not something a person would want to just tune into to fill a day without looking into first. That said, it is really funny and definitely worth watching.
On some levels, this show has a linear plot line that can progress from episode to episode. It deals with an angel and the boy she belongs to and her ability to give him anything he wants. Did I mention he is really, really, obsessed with females and their undergarments? Well, that comes up a lot, as does his connection to his childhood friend/neighbor/possible love interest. There are two other characters as well, the class president and the boy who wants to fly, and another angel evening out a cast that adds a lot to the humor.
Here's an example of a plot line, to see if it is something you would watch, noting this is done with humor but that it also involves some nudity and crass comments/suggestions. Having caused an issue with his angel that ended up causing a flock of flying lady's undergarments, our main ends up with a home filled with colors that the growing boy covets. His neighbor, not thrilled, asks the angel for help and gets her to make any of these our main looks at to explode. This leads to a lot of issues for him considering how the put them on everything, walls, lines, even the goldfish. (wording chosen so not to be edited)
You also have a more serious portion of the show that deals with the angel and its original intent. It was apparently quite the killer in the past and Heaven wants it back. Apparently many male angels are sadists, too, and they send another angle to retrieve the first. This storyline brings some violence to the show, and it also makes one understand even more why this type of angel exists.
5/5, just be aware of the type of show you're getting. also, get this on bluRay while its around because it is definitely much better to watch, with a lot better sound than the SD format.
