Definitely not the best of Big Bang episodes. We see a bit of everyone here. Sheldon did his usual part playing his paranoid self. Howard hooks up with Leslie and ends up getting expensive research equipment and a trip to Geneva. Raj was there to provide the filler bits.
Though the story was more of a drag, there were a couple of good oneliners that made the installment watchable. A lot of stuff was very predictable, and the acting seemed a lot wary this time. We had a paintball war scene, something we've already seen in Gary Unmarried. Just one word to sum it all: average.
