Never did like Blackadder. Have to admit it could be rooted in a lifelong loathing of Ben Elton, allied to a dislike of and disdain for Rowan Atkinson, but I always found it - insofar as I saw it - laboured and predictable in a way that anything Elton ever did always was. All 'He's more cunning than a cunning fox of cunningness at the University of Cunningtown' sort of thing. Oh go and sit down in the corner and play with the bricks, won't you?
Whereas Monty Python were a mix of anything from brilliant to genuinely dire. They were almost always trying something unpredictable. When it came off, it could be inspired. When it didn't, embarrassingly dull and unfunny. But you always knew that 'there'll be another one along in a minute', and you never knew what that 'one' would be like. With Blackadder, the 'ones' were all the same. And I for one found them formulaic, repetitive, predictable...
As Archie said, funny how people see things (differently)...
