I too will use any excuse to proselytize Andor. Speaking of Andor, it's the best Star Wars anything of all time and some of the best TV period.
How I Met Your Mother was a very popular show.
But when I watched it, I was struck by the fact that in many, many places where an ordinary sitcom would have a joke, HIMYM instead had a continuity reference. Everything about the structure of the scene would suggest that the reference had been a comical beat, and the laugh track would play, but there was not even the faintest suggestion of... a joke.
If I want to hear about things that happened in the original movies, I can watch them. Does referring to them improve Andor somehow?
I believe this more intense effect, at least for me, stems from the connection to the unique 'pathos' of the original three films. That's my two cents.
