Warning, there are major yetnecessaryspoilers forLast Breathin this article.
Duncan is portrayed as something of a father figure for Chris.
Duncan is protective of his crew, and he takes pride in his work.

In contrast, Dave is gruff and standoffish.
He is efficient and direct, and he keeps his emotions to himself.
But when tragedy strikes, everyone comes together.

Duncan refuses to leave Chris behind.
The movie makes it all seem so easy (relatively speaking).
And then theres the biggest moment of unbelievability.
[Last spoiler warning!
]When Chris is brought into the diving bell, hes been without oxygen for about 30 minutes.
His skin is blue, but a few moments after Duncan administers CPR, Chris wakes up.
No further medical attention is shown, and we are told he suffered no brain damage.
IfLastBreathwere a fictional film, it would be too much of a stretch to be entertaining.
But its not fictional.
Thats whatactually happenedto the real Chris Lemons.
Many people might dismiss it as too corny.
A melodrama disguised as a feel-good survival thriller.
I dont know how I feel about it.
It is an amazing story.
Of that, there is no doubt.
Dont get me wrong, the cast is great, and the underwater sequences are compelling.
Why would they tell this true story if it ended in tragedy?
For me, that made the drama less dramatic, and the tension less tense.
