If you've watched fight club then this won't be surprising

Rating: 7/10 (2 January 2020)

I found it to be quite analogical to fight club but instead, my best guess, they deliberately pointed out he was kind of troubled and needed to sort out everything.
It's funny how your routine, if not followed properly, will affect you this much and that's quite acceptable.
I didn't feel this was something brilliant but was well served to the audience.
Only if I had watched this before fight club, I would have definitely liked it more.
Not to be ignored, Christian Bale with his 'leaner' body (must have definitely faced problems then) portrayed it brilliantly and you can't just deny that!
