I would've much rather had the voice actor who did Megatron's voice from the G1 series for Megs in the movie. I like Hugo, but IMO his voice wasn't all that vital to the role of Megs and was barely recognizable after they did post.
I would've much rather preferred the G1 or Galvatron voice as opposed to the snarling, grunting beast like Megs voice we got in the series.
However, I hope Megs/Galv is not the shiny silver bot that Optimus was beating up on when the blackbot (possibly Lockdown) blasted him in the chest. That bot looks like a megazord.
