There are more levels of meaning to this film than may be obvious. With the number of highbrow story elements compressed into 100 mins (causality loops, DNA coded missing mass, Egyptian mythology and catastrophism) it would have been very easy to overwhelm and confuse the audience with too many ideas - but Boss Level doesn't. The story is well told, very well paced and seems to make a point of intentionally evolving from chaotic and complex to calm and clear. Clive Ventor's plan is horrific but logical and it's eventually revealed that Roy Pulver really only ever had one job from the start. When he devises his final, final, final, FINAL plan, despite everything that's happened, it makes perfect sense and also provides a valuable message about not giving up - even when you know the situation is completely hopeless.
What could have been just a nihilistic Groundhog Day shoot 'em up turns out to be something far more intelligent and emotionally engaging. Good ending too.
