I usually rave about that show, and yes, it's been 30 years since I first watched it. That's how good it is, and although the pacing may feel dated here and there, for some, I still love it.
This episode, though. Ed's subplot is nice, but purely visual. A tribute to an infamous director, but only by showing characters of his movies. Nothing more, nothing less. Almost no dialogue.
The new guy, Mike, is kind of boring. His condition is the topic of almost every other scene, and it gets old faster than an egg sandwich. Plus, there is abolutely NO chemistry between him and Maggie.
My biggest gripe I have with Marilyn. Although yes, they designed the character to be that way, but it's still boring. The lines are spoken as monotonously as her facial expressions are. Whenever he has more than 30 seconds of screen time and more than two lines in a scene, my feet fall asleep.
To add insult to injury: the whole story has already been done and is a complete replay.
The performers in costume I really liked. Together with said Ed-scenes, the episode was pretty, and pretty absurd.
