I have played every halo game out there and am a huge fan of Master Chief and Cortona. That being said, Master Chief has never removed his helmet (okay if you played on Legendary on Halo 4 he did). I commend Pablo for a great job acting but I think what the showrunners should have done was have the actor lip-sync with the voice of the John from the games...That is the voice I though I would hear. But what really irked me was the sex scene with that human who is supposedly the blessed one according to the Covenant. Throughout the games one thing was clear...Master Chief was in love with Cortona. It was not just a symbiotic relationship but I believe he had real feelings for her and if she were human things may have been different. As soon as he climbed into bed with that woman I was screaming at the television "Master Chief doesn't have Sex!!!!!!!!!!!!" after that it was all downhill for me.
