I don't think Samantha is working out at TWC, as TWC originally intended she would. Remember when she replaced Kelly on Weekend View. That tenure was not long. I don't mind Samantha at all, and I actually don't mind her on PM Edition, mainly because I'm a fan of Betty Davis.
One bug-a-boo that TWC has encountered with new hires in recent years is that just because you do a nice weather cast on the local station doesn't mean you can sustain a TWC show.
Remember when Kevin Robinson was first hired he was filling in on Evening Edition after he'd only been at TWC for about a month. Seen him there lately?
The only new hire that was ready for prime time on arrival in the last few years was Nicole Mitchell.
They hired Sam to do Weekend View - that didn't work - and she's not working out on PM Edition either. They need to toss her in a lower profile spot to develop with a long time OCM - maybe weekends with Dave Schwartz. Right now PM Edition is two rookies with no chemistry.
Who would be better on PM Edition? Carl and Kristina? Every time I watch Carl I ask myself, how does he not have a weekday slot? But I think TWC prefers to keep him as the primary fill in for PM Edition, Abrams and Bettes, and EE.
I think they should move an established team with good chemistry to that slot. Both the Rich/Sharon and Adam/Kristin have developed into outstanding pairings, with good chemistry and presentation. I've posted this before, but I wouldn't be that shocked to see either team moved to PM Edition within the next few months.
Then, move Carl/Kristina to EE Weekend, and Sam or Betty with Dave Schwartz to PME Weekend. The other one can fill in for whoever covers Alex's slot while she's on leave (I am betting on Kim Perez to Evening Edition...).
