How I Met Your Mother will go down as one of the better comedies of all-time (and rightfully so) but there's no doubt as to who's the best part of the show and that's Neil Patrick Harris (Barney)! He steals every scene that he's in and is funny in just about every episode. The entire main cast (Harris, Josh Radnor, Jason Segal, Cobie Smuthers and Alyson Hannigan) is great which makes this show so funny. The first season isn't as good so you may have to power through it out it's well worth it. Also, as most have already said...it has one of the worst finales to a show in the history of television! If for some reason you're one of the few people who haven't seen this yet then I highly recommend you do. It's almost impossible not to smile and have a good time during this show.
