This had all the feel of a "filler" episode but was still good for a few laughs, if not hitting the high notes.
Primarily centered on Leonard and Sheldon, with an aside of the three girls, I didn't get any sense of coherence during the show.
I believe the addition of the other two girls as a foil for Penny has been a good idea right from their introduction but this episode fell pretty flat for me, with the back story for them not raising my interest much.
I much prefer it when the boys and girls interact as this provides balance for the comedy.
I suppose there will now be a few weeks gap 'till the next episode and I have to say that this is one aspect of American TV shows that rankles on me as a Brit.
Pretty much all British shows have a Christmas "special" (usually filmed earlier in the year, of course) that tides the watchers over the holiday period and I wish the American system would follow suit.
Anyway, a decent episode but not filled with belly laughs, this week.
