I am a huge HIMYM fan so I thought I'd give this show a watch (with very low expectations). So far, none of the episodes have really interested me and the jokes have consistently fell flat. This episode was the first episode that I actually enjoyed thoroughly. The chemistry felt different in this one (in a good way) and I hope it continues in the that direction. I'm glad this show got renewed for second season and I hope this episode is an indicator for better episodes in the future.
My one gripe with the show still is the sister character. I feel bad for saying this but she's not funny and I feel like she doesn't have chemistry with anyone else. I hope they get rid of her and replace her with Josh Peck's character. I don't think Sophie and Drew will wind up together (since it's the first season) but I would love to see them pull off a Ted/Robin thing where they remain in the same group as friends.
