I think weird acting styles can be part of the joy of watching older media. Seems like films mostly switched over to "modern" acting in the 70s (?) and TV had a lot more variety in style (and quality lol) way up into the "modern era".

I'm not gonna say "it's not worse it's just different", coz TBH... It's worse lol. If modern acting was a rare minority style of practice I would seek it out voraciously. But, for the variety I do think it's fun to watch old stuff too!
