Thursday, January 7, 2021 Friends is one of the most loved TV series around, years after it was first released. There are 236 episodes in total, and die-hard fans know the words to every single one. The fans have spoken though, and there's one episode that stands out as the most loathed. It comes as no surprise that Emily is at the heart of it. The least favourite episode is 'The One With The Invitation' from season four. This is according to fans rating instalments on IMDB. In this episode, Rachel receives an invitation to Ross and Emily’s wedding. The invite was sent after much thought (and more than a little disapproval from Emily). Ross decided it was a good idea to invite his ex-girlfriend to their wedding in London. Rachel knows it's a bad idea as she still loves Ross and doesn't want to see him marrying another woman.
