Summary
Socially awkward Nathan Caine works as an assistant manager for a trust credit union in San Diego and has congential insensitivity to pain with anhidrosis (CIPA).
On Christmas Eve, three men dressed as Santa rob the credit union and their leader Simon takes Nate's love interest Sherry hostage.
After impulsively stealing a cop car, Nate gives chase and uses genetic disorder to his advantage.
Survive & thrive
Considering the central concept is basically Kick-Ass, search and rescue mission should have been a lot more fun than what it actually is.
As a side note, there's also an Indian film called Mard Ko Dard Nahi Hota (The Man Who Feels No Pain), whose main character has the same condition and embarks on a revenge mission.
Anyway.
Sherry is Simon's sister and was in on heist from the beginning, but developed genuine feelings for Nate.
There's some nice choreography and bloody violence, but tone is consistently all over the place and can't make up its mind if we're supposed to laugh or cringe.
Case in point is Andre pulling off Nate's fingernails with a pair of pliers. During which, Nate feigns injury waiting for online gamer Roscoe to arrive.
The main problem is that Nate isn't The Terminator or a fucking superhero, so I'm certain a normal human being (no matter how tough) would die from the amount of punishment he sustains.
Some things of note.
Kickboxer (1989)
While fighting tattooist Zeno, the ground gets covered in glass which Nate repeatedly punches to embed fragments into fists.
Kurt and Tong Po fight the "ancient way", wrapping their hands in hemp rope, which are then coated with resin and finally dipped into broken glass. Sequence was famously parodied in Hot Shots! Part Deux.
Mortal Kombat 1 (2023)
Nate breaking his arm and using exposed bone to kill Simon is extremely similar to Havik's RAD-ius Incision fatality.
