"BBB" has engaging characters, a fantastic world and a pretty interesting story, would love to see a 3rd season as it's one of my favorites, and remains so even on the 2nd watch.
Pros:
- Colorful characters with some depth.
- Unique world.
- Higher level of art and imagery than average.
- Quality and consistent animation.
- Engaging story.
- Power comes with a price.
- Good range of emotions, from humor to heartache.
- Above average English dubbing.
- Story arcs have resolution.
- Success is is often bittersweet.
- Every episode feeds into the main Arc in one way or another (1st Season).
- Great soundtrack.
Cons:
- Some of the alternative animations to show emotion etc can be a bit cheesy.
- OVA's a huge pain to find, and don't have dubbed versions at the moment.
- Like many anime's the 2nd season is weaker.
