There's some serious complaining about the removable helmet to the point I think some are gonna jump off a cliff, but like Anton said I think you just leave it on and ignore it... I'd rather have A removable helmet than NO removable helmet, even if the likeness underneath isn't my thing.
That said, I'm not Jango Clone fan either so I agree it's disappointing it's not generic, but it is still cool I think. I'm with you there.
The cool thing, at least for customizing, is the head is semi-generic in that if painted differently it will look like anyone, more or less. The hood really helps with that.
