Eureka Seven (only talking about Season 1, not AO) is another very well done series by BONES. E7 is a lot of things all put together in one 50-episode package from action-mecha to SOL to philosophical piece, but the true heart of this series is the developing romance and characterization between the two leads Renton and Eureka. This is the one thing that remains constant throughout the series entire run, gets developed very well and imo is the strength of the series (although Renton can get on my nerves at times). The rest of the large cast is excellently developed in particular Holland who serves as a dynamic and intriguing foil to Renton. The action and animation stand the test of time and still look great. I also like how Bones ambitiously incorporates tons of elements and themes from previous sci-fi and mecha franchises (hello EVA). The biggest weakness for the series is that there isn't a very clear overarching plot for the first half of the series and there are quite a few filler episodes dispersed throughout (even though they are enjoyable). Thus, if you don't keep at it, this is definitely not the easiest series to finish with its 50 episode length. Still, this series does a lot more things right than wrong and is very enjoyable to watch all the way through. Just avoid Astral Ocean...

Okay just let‘s pretend season 2 never happened.

Apart from that it was a great show:)

New movie trilogy

hopefully its more similar to the manga then to AO

Season 2 (Astral Ocean) - a bad sequel and, taken standalone, a bad show. Awful directing, annoying one-dimensional characters, a messy, convoluted plot. Overall, just bad.
Even if you liked E7, I wouldn't recommend this.
