... where whenever I watch a movie or something, I can't tell if someone is being a good or bad actor.
Okay, I guess I can tell when the acting is obviously bad.
Well... I have actually acted on stage before, when I was younger. (last time I acted on stage though was when I was 16)
I remember though that in one school, I went to, we had improv class. And I remember that I was told once that every time I was absent, the improv class felt a bit lacking. (I guess they thought my improv skills were good)
I don't know if I was a good actor though. I didn't feel like I was like those super good actors.
I know that every time I watch a kdrama, I can't tell if someone is a good or bad actor.
I have sometimes seen people say that some actor is bad at acting, and when I watch this actor acting, I don't even think about it.
