Oh horrors, it wasn't realistic
Well no sh__t!
If I quit watching everything on tv that wasn't realistic I would be stuck watching a blank screen. Cops on cop shows don't act like cops, court rooms in real life are incredibly BORING, as an ex soldier, shows about the military sometimes make me cringe, but I ignore the errors, and I'm certain firefighting wouldn't make a great drama either. If you want realism perhaps reality tv suits you better? Probably not, since it isn't real either.
The guy who wrote the review who takes such offense at the fact that firefighting isn't really like that needs to grow up or just quit watching tv and stick to watching people in the local mall.
