A series so good that you can't actually find the best dub. Seriously, the Funimation dub was perfect, but was a limited print before Harmony Gold ruined everything all over again.
Puelli Magi Madoka Magic
If you are reading this list, liked my previous suggestion, and have not watched Madoka because you think it sissy, then go meditate under the ancient waterfall of masculinity and Uro-butch-up at the foot of Mount Manhood to recall how wonderful magical girl shows can be before taking this show in. I cannot explain this series, for to explain it is to ruin it.
El Hazard the Magnificent World
A nerd, a girl, a teacher, and a jerk get sent to another dimension by a magical being they find in ancient ruins buried under the school. I hate so many Isekai, because they used to be so much better. Going back ten years vastly improves the quality of Isekai, so you should go back about thirty years and see what awesome is with this show.
A show where some girl with too much money hires a guy with superpowers to hunt monsters enchanted by magic meteorites. This series is something that should not exist. It uses some of the most cliche tropes, but somehow actually pulls together and is pretty darn good too. Making garbage tropes good is a rare thing.
I chose to use the amazing and funny AMV for this rather than just a pic, because the AMV is just that awesome.
Read or Die
A bookworm girl who can control paper by will goes to stop an evil plot with supervillains in an alternate timeline where the sun never set on Britain. Her and her companions work for a secret society watching over supernatural matters. A good action romp OVA series with an televised anime series after it. Also, there is a manga series apparently that is also great.
