I beleive General Grevious to be the most underrated villain of any franchise ever.Sure the fans love him as do they love Darth Maul but General Grevious is bad to the uh, well i was about to say bone but then he doesnt have any bones anymore.
Anyway, the comic is a decent representation of General Grevious and its fun to read but i think that the art is weak.
And i must say, what is wrong with Yoda?
on page 7 he looks like a zombie on 6 he looks like a evil sadistic ruler with way too much power for his own good.
Sorry but to me Yoda is not only the coolest character ever but he is also the coolest person that there ever will be in fiction writing.
One thing that this comic fails to recognize is that every emotion or facial expression that a character has should match that situation and how the charactor should respond  accordingly to that.
One other thing;    Every comic should have amazing art.We are talking about professionals arnt we.C'mon if i could do better and i only draw about three pages every 2 months and im novice then i expect nothing less from professionals within the business that should outshine me in every way.
