What do people think of John Simms master? Does he work? Did Colin Baker, as another point?

I personally think every doctor has done their best to play for their role, as well as the enemies. David Tennant is odd though.What do people think of John Simms master? Does he work? Did Colin Baker, as another point?
Personaly, I think David Tennant is the best one.





{I grew up watching Sylvester McCoy, and I've seen repeats of Jon Pertwee and Tom Baker}.





DT is a natural eccentric, which is why he is so good in the role.





I thought John Simm was excellent as The Master.








I didn't like Christopher Ecleston - for me, he just wasn't right.
