The problem of Max Steel it is how bad the marketing side has been. Mattel doesnt know how to sell Max Steel to the US or most of the countries that is the problem.
For me, The First Season of Max Steel (Reboot), was perfect the best adaptation of the character, the problem was that the marketing didnt work, it is Max Steel this character from 2.000 who almost no one knows about is sad but true.
They made a movie base in the first 3 episodes of the 1 season (a really bad idea, they should have done their own story base in the reboot setting, because Sidney is a really bland character), and they let that movie in the air for like 2 years.
Max Steel had a nice moment in early 2014, but know is dead again, in Latin American markets maybe will work but in US i dont know why keeps failing.
Is like Power Rangers, for me that doesnt work anymore and they are doing a movie too.
