The problem with The Event right now is that it's boring. I could care less about how stupid everything is if it were remotely interesting, but it isn't. Unlike FlashForward, which actually maintained mystery towards the end, The Event has become a straightforward action show with characters that all seem roughly the same, the exception being Jarvis who is far dumber than any other character (and that's saying something). Plot threads that seemed somewhat interesting or could grow--the girls who looked really old, a possible love triangle (yes, I'm partially advocating for a love triangle!)--have been dropped.
We're stuck with this flu getting released while the good guys try to stop it. No twists or anything, just predictable plot. Even the stakes don't seem that high. As much as the writers try to throw in factoids about the Spanish Flu and how this variant is far deadlier, it's the flu! In an age where we can drop by a drug store for medicine, the name of flu doesn't seem that scarier, no matter how the deadly it may actually be.
