There are too many things wrong with this episode to list them all but to sum up - Unwatchable. Bike riders wearing chain mail? After hijacking the truck why didn't they just stop it to get the "virus"? Why was there a ramp conveniently located in the back of the truck?
Next, remember from school nano means extremely small - like 10^-9. Anything on a nano scale is not going to be visible. Michael is chasing what looks to be a super fast worm with a cloaking device. What's next: a villain made up of light or consisting of a few subatomic particles?
This episode is just dumb, dumb, dumb and no wonder the series is being cut short. I agree with an earlier reviewer who wondered why they cancelled My Own Worst Enemy and bought a whole season of this? Someone with this show must have some dirt on an NBC exec.
