Gatchaman Crowds is about Gatchaman warriors assigned to stop evil aliens that threaten humanity and other things. The series focuses on heroine who becomes one of the Gatchaman.
First of all, I find that main heroine very oblivious and stupid but surprisingly funny or interesting at the same time. Are the creators starting an anti-hero kinda or it's just to confuse people? Anyway, they seem to have a done a great job on that. I rarely see main characters like those in other anime which will probably give this series a unique twist.
Besides our strange heroine, the futuristic setting looks so cool along with the Gachaman in combat suits (quite similar to Tiger and Bunny). Also the combat scenes they do looks alright even though I'm not fondly huge of CG (computer graphics 3D modeling). So other than, this series looks promising and I can't wait for the next one.
Conclusion: An interesting sci-fi action series and definitely waiting for the next.
