Gunslinger Girl: personally, I'd just stick with the first season; the second season's animation put me off terribly)
Axis Power Hetalia: around 50 episodes for both season, I think, but they're only five minutes each)
Bakemonogatari: 12, dunno if subs have come out for the web episodes, or will at all. It might not be a problem?
Pani Poni Dash: 26 episodes.
Jigoku Shoujo: 26 episodes each season; it's mostly episodic until the last few episodes of each season (they tried to make a story in the third season, but it didn't really come together until the last ones again). If you want creepy, stick with the first season. The other two try to insert more comedy.
Speed Grapher: 24 episodes. Pretty interesting and really dark.
Red Garden: I liked the story and the animation enough. But sometimes they sing (like this one time when they were having a small party) and IDK how the original went about it but the dub was awkward as hell.
