The positives I've gathered from the Gatchaman criticisms on wikipedia (9/19/2013)

So far:
Pros:

• The opening fight is excellent, just so extreme. Seems like the 199 Super Sentai Senshi battle.
• The actress portraying the nemesis. She seems to mix ham and seriousness like a perfectionist chef's omelet deli sandwich.

Con:

• Marriage scheme to get into the nemesis' palace.

What we have to wait to see:
The technical jargon: It's an anime. They do it in Star Trek and very little criticism is given about it. (I criticize it.) Anime follows the same suit since.
The cast and acting: There have been complaints about hamming it up and not being Oscar worthy. It honestly was not like we were expecting that.
The special effects: This is not a $200 million budget movie. Fans did not expect it to be.
