Seasons 1-3 of HIMYM were without a doubt my favorite show on TV, season 4 was hit or miss, season 5 was awful, and season 6 is working its way back on track. I just love the story and all of the things that go into it. For a lot of season 5, they got away from the story of how Ted meets ______ and instead focused on a handful of side stories, bad idea. There were a couple of funny moments but nothing that added to the story of the show in a meaningful way.
Still, HIMYM is my favorite show on television. My uncle and I speak in How I Met Your Mother whether it be quotes, references, speculation, or just discussion. And to be perfectly honest I hope they continue on the track they've started for this season, prepare us for the end of the series, and close it out this season or next. At this point, that's the best thing for the show and will help it to hold its "legacy" for me, at least.
