Halley Wolowitz (voice)


It's early January, 2017, and Leonard and Penny are hosting a regular dinner for their friends, the first time they've gotten together since the holidays. Each group has a story to tell which marred their holidays. Sheldon and Amy went to Texas to spend the holidays with Mary. Their issue revolves around the fact that, on Amy's initiative, they told fundamentalist Christian Mary about their cohabitation outside of wedlock. It is not only Mary's reaction to the news that has Sheldon irked, but also a secret that Amy divulges about that news. Leonard and Penny's story revolves around the day they ended up purchasing their Christmas tree, issues around which placed a pall on everything else that happened that day. And in the collective Wolowitz-Rostenkowski-Bloom household with Koothrappali thrown into the mix, they are still getting used to having baby Halley in their lives and the lack of sleep that she causes, especially in trying to get her to stop crying. It's not only the crying ... Written by Huggo

Well this is going downhill, isn't it.
31 January 2017 | by (Denmark) – See all my reviews

Contrary to what many (clearly) seem to think about The Big Bang Theory, I still believe it has its merits. I have been overwhelmingly entertained for almost 10 years now, but today was not the case. The premise was quite well written and executed, but almost half of the episode was nothing but a total let down. Should I decide to re-watch the series from the beginning until the end (so far), this is the one and only episode I would skip, and that's without any question what so ever. This episode adds nothing of value at all, and I am shocked that this made it to television. The first 9 minutes and 26 seconds were a pretty TBBT average 7, the remaining 11 minutes and 40 second dragged it down to a 2 of 10.
