I am in two minds and think it depends on the reason, the sensitivity that prevails and the deceased's wishes.
I'll give two examples.
When FIL died, SIL1, who lives thousands of miles away, decided she wouldn't attend his funeral because it would be too stressful for her. It was all about her. No way.
MIL, who is almost 89 and is no longer able to travel was provided with a video link for her brother's funeral. DH attended on her behalf and when he next visited offered to show her the video. She couldn't do it on her own and preferred him to take her to church where she could pray, light a candle and hear her brother's name mentioned in the intercessions. Absolutely fine.
Because of this thread I am going to discuss this with DH with a view to amending our wills with our wishes. It will be a no from me unless there are very close people who cannot attend for legitimate health reasons in which case it will be a link just for them and time limited for one watch. It's a funeral, nor a circus.
Reflecting, however, how many watched Prince Philip's, The Queen's and before that, Diana, PoW's, funerals on TV? Many I expect and there's a bit of me that says what's sauce for the goose, is sauce for the gander. I didn't, I thought it mawkish.
