It truly is unwatchable..
I know I'm relatively late to the party, but jeez... Normally shows with bad seasons I can just overlook them. If the bad seasons occur mid the shows run, and it improves. I can get past it! If a show ends on a bad note, most of the time I can get past it. How I Met Your Mother season 9, and even season 8, and especially the infamous finale have actually killed this entire show. I can't get in to it at all now, even with the earlier episodes.
Anyone else have this problem? I mean Big Bang has lost its way, and I can still enjoy the earlier seasons just as much as I did the first time. I enjoy X Files despite its lost direction. What is it with How I Met Your Mother? Anyone else just not able to see it in the same light anymore?
