These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Iron Woobie: Taylor. His wife dies in what is suggested to be very poor circumstances (he was ready to commit suicide over the fact) which in turn causes a life-long hatred towards him by his son. And then Washington, someone implied to have helped him over his issues, gets killed during an attack on what now amounts to Taylor's life's work — preserving humanity's future from really evil forces.
Just Here for Godzilla: Many people probably only watched this show because DINOSAURS, and were probably very disappointed that there was only about six minutes worth of dinosaurs in the entire show.
The Scrappy: Josh is overall considered pretty unlikable mainly from the pilot.
Unfortunate Implications: Terra Nova is, to put it bluntly, a military dictatorship led solely by Commander Taylor. Not only does he make all political decisions, he also acts as judge, jury, and executioner in criminal matters. Yet the series treats this as pretty close to an ideal state. Jim even says that Commander Taylor's method of handling trials is much better than the judicial system back home, where the accused actually has rights.
