You want the widescreen version of the Bourne movies because they were staged and composed that way intentionally.
If you choose fullscreen, you're seeing criminally compromised images in that Bourne might be fighting someone in the frame as intended, but fullscreen would most likely have just Bourne in the frame punching & kicking an unseen someone.
Or take another example, a dramatic face-to-face conversation with two people visible in the frame is changed to just a shot of one person.
I'm not sure if all fullscreen versions are generated via pan and scan, but check out these images for illustrations of the butchering:
