HIMYM started out as a solid sitcom with a great cast that really pulled off the ensemble well. But it was way too limited a premise - how long could they drag out the question of who the mother was? Even in its fine first season I thought this could go on for two seasons - maybe three. Instead it went on for nine and by last few seasons the writers were scraping the bottom of the barrel for ideas. It was AWFUL. I could only look in occasionally on the show during the last two seasons, watching the episodes where I’d heard that something real might happen. And I watched the miserable series finale. Really miserable, a travesty.
It’s really too bad when they have a TV show that starts out with a really bright and creative idea and then they try to stretch it out season after season because the viewers keep tuning in. Over the past decade I can think of other examples such as Once Upon a Time, Sleepy Hollow, Empire, and possibly This Is Us (remains to be seen).
I had a lot of fun watching HIMYM in its early seasons. There were several Buffy- and Angel-verse actors who made guest appearances on HIMYM - Alexis Denisof, Harry Groener (the Mayor), Tom Lenk, Amy Acker and whomever else I’ve missed. But I resent the show for ruining Alyson Hannigan for me. I’m not a fan of sitcoms, I only tuned in initially because she was in the cast and I liked her character at the beginning. As the show went on and on the tired writing made AH’s character Lily Aldrin ever more insufferable. Finally she became unwatchable. I still love Willow from Buffy but unfortunately when I see Alyson Hannigan on TV nowadays she brings late show Lily to mind more than Willow. I should have quit HIMYM earlier.
