I honestly loved the concept and would probably have been a customer if I could afford it.
Contrary to your description, it was mostly celebrities doing custom greetings for fans, sometimes as themselves, sometimes in character and usually bought for people as a surprise gift.
Amongst others, there was Jim Rash wishing a Community fan a happy birthday in character as Dean Pelton and dozens if not hundreds of short to medium length videos of Dave Mustaine from Megadeth recording super wholesome and sincere messages for specific fans.
Can you honestly tell me that doesn’t sound great?
