I really wish they weren't sisters, their chemistry is too amazing.

It's so true. They are adorable x infinity + one together.

I just started watching Fringe because I heard it was done by the same people who created Lost, and now I am totally hooked.

Good, ol' JJ. He also did Alias, which was a pretty good show. Alias also had a sister/sister pairing with uncomfortable amounts of chemistry. I don't think JJ understand how sisters should interact with each other, lol
