Factual error: The solar eclipses in the show that affected the characters' powers were referred to several times as "global events". In the episode with the second eclipse it's shown to be visible in locations thousands of kilometers away from each other at the same time. This is simply impossible, since a solar eclipse occurs when the moon passes between the Earth and the sun, casting a moving shadow that can be only about 250 km in diameter (for a total eclipse). The partial eclipse can be viewed in a much wider region, but the eclipse in the show was a total one. It's not a global event, but a local one.
Heroes (2006)
1 factual error in show generally - chronological order
Starring: Hayden Panettiere, Milo Ventimiglia, Jack Coleman, Masi Oka
Plot hole: If Noah could be brought back from the dead with Claire's blood why couldn't they bring back Nathan? Was turning Sylar into Nathan really the first thing they could think of?
Hiro Nakamura: Save the cheerleader, save the world.
Trivia: There are a number of other Star Trek references in Heroes. In episode 15 (Run!), Hope refers to Hiro as "Sulu." George Takei, who played the original Sulu plays Hiro's father. And at one point (and several other times throughout the show) Hiro gives the Vulcan hand symbol that Spock always used when he would say "live long and prosper." Zachary Quinto, who plays Sylar, would also later play Spock in the 2009 reboot Star Trek.
Question: Hope the showgirl locks Hiro in a small closet. He makes several unsuccessful attempts to escape by running and charging towards the door. Why doesn't he simply teleport out? Surely a lot simpler and a lot less painful?
Chosen answer: Hiro's powers are still quite unreliable, and a locked closet door isn't a huge obstacle. Since Hiro knows he needs to rescue Ando, it's probably safer to try and bash the door down than risk teleporting to the wrong place or time.
