I get people feeling sad as it's someone a lot of us grew up watching. He was young to die and his story is sad.
However I've noticed a lot of people talking as if Matthew Perry created Chandler. He acted and he did it extremely well as did the others with their characters. He made the character of Chandler come alive.
But he acted a script that was given to him. And yes he was allowed input with the writers and came up with some funny jokes that were used. He was clearly very funny. But that's not the same as writing all of the scripts and doing it as a full time job.
There's people online praising Matthew Perry for all of their favourite quotes, for things they liked about Chandlers personality etc which I find odd. Often people (not you OP) seem to forget that writers exist and think their favourite actor created the character and improvises all of their lines.
Liking Chandler doesn't mean we knew Matthew Perry at all. If anything, knowing Chandler probably means you know the writers more than Matthew.
Then there's the way that all people can talk about is how much grief the rest of the cast must be feeling. And I'm sure they are genuinely devastated. But at the end of the day they were colleagues. Colleagues who worked very closely together and probably did become friends. But the way some of them spoke it was clear they often didn't see each other for long periods of time. It's natural and there's nothing wrong with that. It doesn't mean they won't be devastated by the news. But surely it's nothing compared to his actual friends and family are feeling. They're the ones my thoughts are with primarily.
Earlier on I read someone on Facebook say they'd been waiting for the cast to make a statement as it made them feel less alone with their grief. I find it baffling.
I was a massive friends fan. It got me through some bad times and it always made me feel better. I've seen all the episodes so many times. I cried when it ended.
I am sad that he's gone. I really am. But I didn't know him. None of us did. His parents have lost their child. That's not the way around it should be. Their world has stopped. It's not Chandler they've lost.
