The last in the Men in Black Trilogy took on time travel. It didn't work out very well.
When Men in Black first debuted in theaters way back in 1997, it felt like a new generation's answer to Ghostbusters, only with aliens instead of ghosts. And while the series succeeded where Ghostbusters failed when it actually made its third film, we're not so sure it was worth it.
It seems the gang at Cinema Sins agrees. Their latest video counts down all the sins of Men in Black 3. Surprising no one, most of the sins involve the movie's take on time travel and how it makes absolutely no sense whatsoever.
