The Frost Sisters became... diluted in general, when they started to be more 3 in 1, and less Esme. It came across as too gimmicky.
The faces of the actresses here:
... pretty much says it all, fake half-smiles & all. Even when they were first posted, it looked to me like they could barely muster the effort to try & show they were happy to be there. On their part, I see a lack of enthusiasm, discomfort, perhaps even tension, and just all-around displeasure. I get the impression they'd almost rather be anywhere else.
They'll be remembered as the bane of this show's eXistence, the parents in particular. The mother's bad enough when it's all said & done, but REED... I could barely tolerate his tired, boring-ass, sad & whispery dialogue delivery in this most recent episode. Just kill 'im off already, he's more painful to watch than ever. Sure wish he would've been the one to get pumped full of bullets, instead of Blink.
