Awards should be given to the best actor every year, regardless of whether they had won the previous year. As much as I love Damian Lewis (seriously a cool dude, great actor), Don Draper and Walter White are iconic characters, and while Cranston has gotten his due, the fact that Hamm has yet to win is completely ridiculous. I mean, for my money, the most recent seasons of MM and BB were easily their best, and easily the best acting-wise for the two leads.
The less said about the comedy category in general, the better. Obviously.
