This was a great Scrapyard Wars but, as with many other people, I felt it was a little drawn out with the 7 episode and I kind of stopped being as exciting into the 5/6 episode.
I understand that there were more competitors so it is inevitable but it still lacked the stamina to go on for 7 episodes.
But other than that critique it was a great series. Maybe next time find a way to condense the main story into like a Saga and then have an extra episode or two for people that wanted to know everything that happened behind the scenes and stuff like that (Maybe even how it was filled but that is just an example.)
