These music videos run for about 7 to 8 minutes, and they are promotional openings and closings for an uncreated Shina Dark, a four-volume manga from 2006. There is some nudity, and some bizarre scenes that probably only make sense to those that have read the manga. 

This 4 episode OVA has a run time of about 96 minutes. It features magic panties, arcade games, and some very odd comedy. This is one of the lower rated entries for Shaft for some pretty good reasons. But, maybe you'll like it?

This 12 episode anime runs around 5 hours and is honestly geared towards loli lovers. The main character is now the servant of an immortal vampire with the body of a twelve year old and a skimpy wardrobe. But the action is interesting, at least. 

This 24 minute recap is pretty much the same entry as the one above, but it's a quick entry. maybe watch the recap right before you review the main entry?

This 12 episode anime (run time 5 hours) took the anime community by storm when it first aired. It takes the idea of magical girls and asks "what are the consequences of giving volatile teenage girls super powers?"

This 130 minute movie covers the first half of the Madoka series. It will feel like a recap, but at least the artwork is a Shaft kaleidoscope. 

This 109 minute movie covers the second half of the Madoka series. Again, it's basically a recap, but now that you've seen the series, maybe look for clues and things you might have missed in the series. 

This 117 minute movie occurs after the main series, and expands on the emotional state of the protagonists, as well as retcons one of the antagonists from the series. 

With 15 full length episodes, it will take about 6 hours to fully watch Bakemonogatari. This makes it one of the longest anime on any of the Short Badge lists. If you want to catch all of the auxillary dialogue, have the pause button ready for thia anime. It is also one of the best examples of the Shaft art style, which is often abstract for no reason. The story follows former vampire Koyomi as he interacts with various supernatural women. Alternatively, you can watch the prequel movie trilogy and Nekomonogatari, which is also a prequel. 

This 24 minute episode recaps the Bakemonogatari episodes 1 through 5. It covers the first two arcs of the show. Not really any new information added, but a decent refresher before you start the third arc.
