I suppose I can enjoy it in much the same way I can get invested in an episode of say, the original star trek from the 1960s. I mean sure, I could sit there and point out how the computers are silly, the physics are un-realisitic, the special effects suck and the alien planets are clearly earth with props. Or even classical theatre. I mean theatre is objectively far more flake or unrealistic than anything pro-wrestling does (wait a minute, they're not in a castle!) But if a story - in any medium - engages me enough I'm willing to look over a lot.

Wrestling has its own set of "in-universe" realities that we the audience are conditioned too. If they're adhered too, and everything makes sense in the logic of that framework, I find it easy to suspend disbelief... provided of course I care about the conflict.
