I'd say the lit up eyes for the MPC were a hated feature. Mainly because the visors don't really light up and the fact that it not only lit up the eyes but the whole head because of the cheap thin plastic they used. I think lights on the control panel and maybe even the boosters would be cool, but more so on a 1/48 Hasegawa or even better a 1/32 premium format toy. But that's more a Bandai thing not a Hasbro feature.
