This is kinda related, but a month ago, I watched a Chris Benoit match for what may be the first time since everything happened 5 years ago. It was his match against William Regal from No Mercy 2006 (It was Benoit's return after some time off, and the PPV with naked Regal running from Vito).
There were some NASTY chops to the face and other hard-hitting stuff that just made me wince every time. I don't know if it was hindsight, knowing what happened or what, but even though it was a good match, it was tough to watch, knowing what I do now about head trauma, and that was all ol' fashioned, unarmed rasslin'.
I can't say I miss chairshots to the head, unprotected or otherwise these days.
To me it varies on the severity of the chair shot. If it's just a guy gettin bopped on the head, solidly but not viciously, cool. But some guys swung the damn thing like a baseball bat as hard as they could back in the Attitude Era, and I hate seeing that now. Taker used to give especially brutal chair shots, he'd lift the thing as high as he could over his 6'10'' head and smash the shit out of people. Looked awesome back then, but now it feels really irresponsible, stupid even.
It looks like WWE nuked the clip off of YouTube, but the whole sequence of Lawler invading ECW is just filled with uncomfortable chair use, and actually, a whole lot of the throw-the-chair-as-hard-as-possible at their unprotected head shots in ECW comes off as even more irresponsible as regular chair shots.
