I think the dedicated gamers who play mech themed video games -certainly the target audience for this show - will be sorely disappointed at the sluggish lumbering ersatz "robots" in this event.
You're forgetting all the mech anime fans AND the legion of fans of the pop culture phenomenon
Real Steel.
(Taking tongue out of cheek, I'm looking forward to this nonetheless. AND I watched Real Steel and discovered it was surprisingly not terrible. Far better than most of what Hollywood puts out. Sort of a "Rocky with Robots." Which, I guess makes it just like the rest of Hollywood: "Take a previously successful movie and do it again!"
Edit: Ah, went back and looked at the plot more. I forgot it also had the whole "Lackwit father saved by son and gets it together in the end.)
