Hate to join the Haters but yeah, Missy didn't really convince me either. Might have worked if we'd first seen her in a couple LoadingReadyRuns etc. to get used to her type of comedy, "acting" etc.
This way - no, sorry, not funny.
The british accent wasn't funny, the "shame over wine" thing was overdone, she looked around too much, too long, etc.
The "I'm a wine addict and ashamed of it when it's brought up" act has potential, she did some of that well, but not nearly enough unfortunately.
But it's an interesting experience - makes us more aware how good the other guys actually are. Just taking that for granted usually but they really have great comedic timing, style.
And, as unfair a criticism that may be, her voice didn't work for me. Catheyln and Gramm both have very appealing voices, they don't .... "raise the level", they flow along nicely. Same goes for everyone else on the LRR team. Missy's voice is too high and a little shrill and took me out of it everytime she spoke.
I know that that sucks and it's unfair etc., just describing my not so great experience with this episode.
