Base-Breaking Character: Farrah Mahmoud, the hospital psychiatrist. On the one hand, many see her as a Designated Villain for Kate. Other times, she's an idiot who constantly gets her own diagnoses wrong, leaving Kate to clean up the mess.
Narm: Will explaining his Dark and Troubled Past to Kate, since it comes off as long and awkward exposition about his backstory, delivered with stilted dialogue.
Replacement Scrappy: The intern who replaces Ali. She has less development, is brash and annoying, and constantly messes up.
The Scrappy: Delilah, Will's one-time affair-cum-stalker. Will has an affair with the waitress Delilah, and she becomes Yandere for him. But can't fire her from his business, as it would look like he's firing her for romantic involvement. After this is brought up, she mainly just exists to cause a minor inconvenience to Will and Kate before, and is eventually fired regardless. Ironically, in a similar situation to Joanne Froggatt post-Robin Hood, her actress had more success after the show was canceled.
Alternate Character Interpretation: Is Thomas dead at the end of the movie? Nolan seems to have full control at the end, and the last we see of Thomas is him stepping onto the void, implying he has ceased existing. However, given that he is basically a digital copy of the original Thomas, whether he is dead, shut down, or is still alive in some form within Nolan's mind has yet to be clarified. Making it even muddier is Dr. Brooks seeing him in the headset at the end.
