The 10 Worst The Big Bang Theory Episodes
6. The Planetarium Collision (Season 12 Episode 5)
In this episode, Sheldon tries to help Amy in a professional capacity by ensuring she has enough time to work on her super-asymmetry theory. As sweet as the gesture is, Sheldon takes over and sabotages her career prospects. Meanwhile, Raj and Howard butt heads when Howard is invited to co-host Raj's show at the planetarium.
Why it sucks: This show is built on jokes about stereotypes and it's impressive to see that even 12 seasons later, the writers still fail to write about anything different. It's clear to see that the show was crawling towards the end in season 12 when the best joke the writers could come up with was when Sheldon mansplains the term mansplaining to Amy. Raj and Howard's squabble is cute and whilst it tried to playfully remind us of the journey the two characters had been through, it was more of a reminder that, once again, the writers hadn't come up with a fresh take on their relationship for over 10 years.
What didn't suck: Bob Newhart appearing as Professor Proton as a force ghost in Sheldon's fantasy whilst the two grab a bite to eat at a diner on Dagobah.
