Don't get me wrong, I hated Lost with a burning passion - I really, really, really did, before anyone else, in fact - but I find everyone involved with that abortion seems to work much better when they're only given a finite amount of script and less of a blank check (i.e., films or in Lindelof's past case, comics). I really can't get onboard the knee-jerk hate train for him or Green, much less conflate the character into the writer.
Now, Holloway seems interesting enough for me in that, as I mentioned before, I wonder if he's been the dominant personality in the relationship with Shaw all along, and if she's been left in his wake up til now. From what little we've seen, she demurrs and defers a bit; he's the driving ego, probably professionally. Which is an interesting dynamic to play with, as is his arrogance. It makes for good drama. He's young, he's handsome, he's a bit of a slickster, he's in love - all apparently verboten in a geek-accredited tough-as-nails Alien movie, but we're not in Kansas anymore, we're in Prometheus. Besides, he's totally going to get butchered anyway, and he'll probably at least partly deserve it.
