Very short man?
A strange, and incorrect, word to use. (BTW, the new Bond is the same height as Bourne and both are above average height.)
There is no need for comparison anyway.
Bourne - an amnesiac assassin from a CIA black-ops program. A loner, without gadgets and cars and Government backing. No missions.
Bond - An Intelligence Officer for Her Majesty's Government. Gadgets, cars, support team, Superiors. Assigned missions.
Different people, different characters, different methoRAB.
Wasn't impressed with Quantum of Solace - just a load of set pieces with no substance.
I find the Bourne movies a bit more demanding of the viewer, and that is a good thing for me. They are certainly not boring.
Bond had become stale. And yes, they did copy elements of Bourne with Casino Royale (a good film).
