It's hard to rate this episode because in my opinion, Fringe is this special type of series where it's better to rate the whole thing than every little piece of it. I will rate every single episode anyway, so I have to say that this episode was beyond just confusing and made like the Walter Bishop character less, however I really enjoyed the mystery about the whole thing. I sincerely hope that this coalesces into a fantastic entirety. Still, the confusion was by far not the only flaw of this episode: never ending illogicality, blatant oddness and a crime, which by the end, nobody gives a crap about. The creators want to keep us watching with this crazy cliffhanger, which seems to make the show more complicated than it already is - after 4 freaking episodes! I could rate this episode really bad because of all these things, but I won't because I believe in the show to become really entertaining eventually and I suspect that I'll like the stuff that just confuses me for now. Furthermore, it's good dialogues and fine acting.
