According to Lena Dunham, she considers this episode a "short-film epilogue" while the preceding episode, Goodbye Tour (2017) is "the more traditional [series] finale".
As a fan of the show I was very excited to see what they did for the shows final episode. I have to say I am very disappointed, it did not even feel like a season finale, let alone the final episode of the complete series.
Because it's 'Girls' I did not expect a big booming final episode but I feel they could have gone more into the other characters as well. The episode just features Hannah and Marnie and I am curious to see what happened to the rest of the cast.
