Who makes the best superhero movies?

Each is a different and separate franchise. Do you understand that now? Or do you need me to explain it to you again?

OK, so now that we've established that the TDK trilogy is a franchise and different and separate form all other DC movie franchises, let's get back to the point. And the point is the TDK trilogy is universally regarded as the best superhero movie franchise ever. So the answer to the question "Who makes the best superhero movies?" is obviously DC since DC made the TDK trilogy, which is still universally regarded as the best superhero movie franchise ever.
