Cracked

Some symbols at the very beginning were math symbols (e.g. Symbol for integration; partial derivatives; summations) when McGee says something like... "Are those some sort of chemical symbols?" Yes. Some of those are chemical symbols but with his degrees he should absolutely have recognized that many were math symbols. Later when Abby is showing Gibbs close ups they are chemical symbols.

On positive side, it was nice to see woman engineers. On the negative side, the victim depicted as being not willing to work on teams, difficult to work with. Sort of classic stereotypes for women engineers. (I'm an engineer, who is female, and am not usually seen as like this at all, nor are most women engineers I know). Lots of stereotypes here. Yeah, i agree with another reviewer, Abby is a bit over the top in this one.
