I was expecting quite a lot from this anime, and I didn't get it. The characters are attractive, the story sounded interesting enough on paper, but it just lacked style. Some of the scripting is so forced and unrealistic that it just makes you squirm with embarrassment. And the fight scenes...erm...they got glossed over. The scenarios and the plot were far too "convenient", pushing the bishounen characters into situations where they could touch each other endearingly (aka inappropriately, yahoo!) and struggle with their inner most feelings (aka lots of angst). Saint Best is a bishounen-fest. There isn't really much else to recommend it. There are only( I think) 2 female characters in it; a goddess who seems to need her strapping lads to do everything for her and a midget angel that bounces about thinking she's being very cute (aka putting "dechu" on the end of every sentence - argh!)
If you're happy with just looking at the characters (lets be fair, they do look nice) then go for it, but I recommend turning off the audio and subs, because otherwise you'll spend a lot of time cringing.
