I have to say, this show really does crack me up.
It's supposed to be a "serious" show involving science solving some unusual occurrances, but the slight humour injected into it does make me chuckle. The cow in the lab really does get a laugh out loud moment, especially when one of the characters wants to feed is strawberries so that they can have strawberry milkshake! Priceless.
The story itself sees two worlds occupying the same space at the same time, and for all intents of purposes, vaguely aware of the other world. It's a fun game then to "spot the differences", such as the alternative world using airships instead of planes, the twin towers still standing, the advent of an ID controlled society, and the absence of the FBI (instead the MOD Fringe Division). The show will take us to missing balconies causing the guests on it to plumet to the ground, disappearing items, ghosts (or alternative world counterparts), plane crashes, people imprisoned in amber nectar for eternity, a cool way to rob a bank, and how a family reacts when dark secrets revealed.
I just hope they go onto a fourth season (and with this product NOT being called "Complete" is a very good sign indeed.)
