The characters in this book are so incredibly dumb. They say idiotic things, like when the girl is trying to get into the library she's on her phone and someone comes out of their room knocking at the house who they think it is, then proceeds to tell her not to. Just dumb stuff. I couldn't finish reading this...

Ex Output:
Bad review

I'm not going to bother commenting on the content of this DVD, because even I feel it is an insult with all the errors and factual mistakes. First the most annoying error -- he has a group sitting in one room talking about the Holocaust without noting that almost every person who ever worked for or was persecuted by Nazis was Jewish, making no distinctions at all: they were all Jews.

Bad review

I find this version of Sherlock Holmes to be more interesting and watchable than the previous adaptations. It's true that Cumberbatch is not Watson. But then, why change Watson's voice? And while Martin Freeman as Lestrade does a nice job, his character is played on a bit too much for my tastes (e.g., when he shouts, "We have just solved our crime!" one can almost picture him shouting it several times throughout every movie). Even Robert Downey Jr.
