Themed episodes are often the Big Bang Theory's finest. There are some tremendous homages to Star Wars littered throughout the series, with a special episode dedicated to the release of The Force Awakens. I'm not saying we want an exact clone of that with Batman vs. Superman, but there should be a big fuss about the film. Many fans want to see the return of the 'geek humour' that made the show popular in the first place. A classic return to that style would be a nice idea for the show to consider, and Batman vs. Superman gives the writers a perfect opportunity to go there.
