‘The Big Bang Theory’ has maintained high ratings it’s entire run. That’s why mean fans found it surprising that Season 12 will be it’s final season. Especially after having 12 years with Jim Parson’s quirky character Sheldon Cooper. His character has also gone through extreme character development. He completely warded off romance at the beginning of the show. Now he’s getting married. Fans hope the series ends just like it’s namesake… with a bang!
