Agree, the Peter story line has traction (plus bonus points for girl w/ accent, yay!) as does Claire's but I swear if I see the stupid Mexican twins use/unuse their powers again to get out of a jamb I'm going to shut it off. And Hiro is a mixed bag right now, if they'd let him move on from yet another repetitive story line (sark is good, sark is a drunk idiot, rinse, repeat) I may be on board but so far I'm not buying it. Did I mention that I hate the Mexican twins yet? I hate the twins.
And Reks, they had ample time to realize that the show was going to have a second season. I mean it was a hit from the get go, so they knew what they needed to do for at least 6 months.
