The Big Bang Theory: 5 Reasons It Needs To End With Season 12
3. The Characters Have Majorly Evolved
From the time we were introduced to the five main characters to how we've come to know them now, it's clear to see how they've all gone through their individual changes.
Sheldon for example started off as being one of the quirkiest television personalities of the past decade. He does still have his eccentric characteristics, but he's now become known to open himself up to people more, including going on to become a husband. Raj is another prime example of major character development in the show, as he can now talk to women confidently without being under the influence of alcohol.
Even the characters who came in later on, such as Amy or Bernadette, have went through their own little changes. Considering the level of progress they've all gone through, what else could they have happen in their lives?
It gets a bit old seeing beloved television characters become stale and stagnant. Is there anyone that would realistically stay tuned to watch the guys play video games or go to conventions while in their older adulthood? While the writers will perhaps have a trick or two up their sleeve, it's best to leave something like this for a singular flash forward episode.
