Average Rating: 6,8/10
(+) All characters end up growing into your heart.
(+) Great accuracy when talking about science, historical events or any type of random fact. Nothing here is made up for comedy.
(+) Does great at capturing nerd-culture, quiet a few people of our generation might see themselves in some character.
(+) Pretty much every episode will make you laugh.
(+) Character evolution takes its time. But at least there is some, unlike in other sitcoms.
(+) Characters are often put into situations that feel relatable and that the audience can learn from.
(+) The characters complement each other to perfect harmony.
(+) With the vast amount of episodes that have been released it seems incredible how the show has managed to keep a good constant level throughout these 12 years.
(+) Great celebrity co-staring in a lot of episodes (Steven Hawking, Bill Gates, Elon Musk, Mark Hamill, etc…).
(-) Acting performances often tend to be rather mediocre.
(-) At least a couple of bad episodes slipped their way into every season.
(-) Jokes regarding character traits end up repeating themselves way too often.
