It's not just you.
Many people noticed Chiana's voice was "off" - at least in the first scene, to be fair, there was no way for even the most brilliant of improvisors (which Gigi clearly is) to force Chiana to believably enact that, let's say, overly simplified scenario. On this occasion, the contacts were okay by me - the novelty device was cool for a one time shot and she didn't really need to act with her eyes. It would've been helpful to have her old eyes mind you; she couldn't even use her eyes in her big finale scene with Jothee because they'd do even worse than not express well, she just got by on her extraordinary way with body language et al. But clearly those cat eye contacts are going to be a profound liability if they continue Chiana for long like that.
Gigi Edgley related at one point (in the nicest way) that there was something which affected her performances. When one takes it fully in context, I think the result was actually a trememdous compliment to Gigi. But she has suggested some qualification for returning and it's easy to see what she'd be referring to and that she'd have entirely valid points.
More than a few I've heard from via the Chiana website were, let's say, worse than merely unsatisfied. For my own part, I expected to see little of Chiana in the mini, but I was frankly a little shocked at the quality of much of it, in a show that was otherwise quite spectacular as a whole. As it is, her part in PKW is mostly quite enjoyable - but best not looked at closely, and that's most unfortuanate. Hopefully, any future Chiana will make us forget all about this. Goodness knows there's much greater potential in her. That much, at least, we could always see
