No one has the right to criticise a show without seeing it first.
M7 certainly had some lows. Those good moments hardly showed up in the first twenty eps. It gets much better towards the end, although are some eps in there that make you go WTF. The ending was excellent though.
Delving more into the history of the Protoculture was the most important aspect of M7. That was one of the main saving graces of the show. I must admit, if things went the same way as the first ten eps, I certainly wouldn't watch it till the end.
