I agree it has a long way to go when it comes to plugging the x Files vacuum and I doubt if it will. You can't really plug a show's vacuum with another show that is,in many ways, the exact same show. Slight deviations in nuance and dynamics occur but let's not kid ourselves here, Fringe is an X Files rip-off (itself an Avengers hommage) , a slightly better rip-off than The Chronicle or Dark Skies - - which , bad as they were, took the effort of not making its Mulder/Scully clones FBI agents.
Plus I agree about the lack of chemistry. A friend and I were talking about this the other day - - the lack of chemistry and how everybody's so uptight and needlessly intense. Mulder and Scully (like Steed and Peel) had chemistry in spades and that was more than half the battle. Regardless of aesthetic motives, chemistry between the two leads should be paramount. And I don't think, at this point, they should even try to get out of the XFiles Ripoff shadow. The show mainly feeds off our love for Grant Morrison-style black science/weird conspiracies. It just has to be well-told (and people say it is, I'm only up to Ep. 4 but it does look good, loved the frozen bus particularly) and , ripoff or no ripoff, all will be forgiven. It already is, I think.
Like I said, I saw the 4th episode recently and yes, the quality does go up quite a bit from Episode 2, which was a mess. Good solid entertainment. The 3rd one was no slouch either. I still have problems with some of the acting. Everybody seems prone to outbursts at the tiniest provocation. It's a little off-putting. And not very realistic. But this was a fairly well-written episode, if only for the revelations and how they put an end to the Oatu/Observer parallels. Plus the dialogue has improved significantly - - - I noticed that Abrams didn't share writing credit with Kurtzman and Orci, so the two may be the culprits. After Whedon (Buffy), Sorkin(WestWing) , Milch(Deadwood) , Moore(BSG), Simon (Wire) and indeed Abrams (Lost) and Christ Carter you sort of half-expect these young turks to take writing pointers. Oh well. The twist ending to this one wasn't surprising , too, since they keep putting Mark Valley's name on the credits, which is sort of like putting Kevin Spacey's name up on the credits of Seven.
I'm cracking the 5th episode soon. It IS a fun ride. Comfort TV. And everybody swears it goes nowhere but up. But i'm shifting to BSG for the meantime.
