I think “Big Bang Theory” is brilliant for many reasons.
It’s very funny and the scripts are very clever. I am not particularly interested in comic books and sci-fi, but I am interested in particle physics and general science. I like the fact that the science is accurate and current. It’s amazing that a comedy can give insights into physics and other science subjects that prompts afterwards looking things up on the internet. The show also portrays psychology and emotions which I find enlightening.
Sheldon is the main star, but all the cast are very good actors. I think that Leonard, Howard and Amy give particularly convincing performances. And Penny is gorgeous and funny!
Sheldon’s eccentricity and his genius level of intelligence are impressive to watch as well as very funny. His performance, each episode, of his huge part of the script is amazing. The whole show is dialogue dense and written with precision. There are some cringe-worthy moments. but not many. The scripts pull in a very broad range of topics and an equally broad range of vocabulary, with correct grammar (otherwise Sheldon gets upset).
I imagine that the “quality” of the English makes it a good show for anyone learning the language. Regarding the DVD’s, I use the show to try to learn Spanish and French. I watch each show twice with English audio. Once with Spanish subtitles and then again with French subtitles (both are available on all series except series 1). The broad English vocabulary and big range of topics is excellent for learning new foreign words. It’s also great that the elaborate sentence structures of the English audio are faithfully retained in all the subtitles (including the English subtitles).
Fantastic funny show, great comedy characters and excellent high quality box set! Great value for money!
