Some of the episodes in the final season (12th) were not as good as others but the final episode with the awarding of the Nobel Prize to Sheldon and Amy was very good and a fitting ending to the program.

My wife and I are huge TBBT fans, already owning the previous 11 seasons on video. We love to not only watch the episodes, but the bonus material, especially the blooper reel. Watching the cast stumble and crack up, not just on the big scientific terms, but on the most basic words, make these fun. If you've never watched the series, there are several box sets so you can follow the storylines from the beginning before you get to the finale. While each episode stands alone, to understand the beginnings and advancement of the characters you have to watch it from the beginning.

Some TV series end with a disappointing thud (ex: Lost), but the ending to one of the best sitcoms on TV went out on a high note. The Big Bang Theory ended before it overstayed it's welcome and it was nice how the gang had a final come together at the end. While it's sad to see it all end, after 12 seasons I could probably go back to the beginning of the series and watch it again...it was that good.

The final season continues with Amy and Sheldon finally married and may have an ideal that may lead to a Nobel Peace Prize. Penny and Leonard talk about starting a family. When I heard this was the last season, I hoped the writers would “fix the elevator” at the closing of the show. It snuck up on me, but I got my wish. Big Bang Theory is one of the all-time best shows in tv history.

By this point you either know what you are getting into with this item or you have picked an odd season to start watching. The series has evolved and is different in some ways and the same in others. This is a proper send off to one of the most popular shows on tv for the past 12 years.
