It makes for a thrilling and intense atmosphere, amping the stakes, and more importantly allows Denzel Washington’s Robert McCall to effectively show off his crazy killing skills in a unique environment.
It’s definitely a whole lot different than the end of the first Equalizer, which you may remember concludes at the hardware superstore at which McCall worked (in the sequel the story picks up with him operating as a Lyft driver).
Without getting into too many details that might spoil the experience of actually watching The Equalizer 2, the pain and struggle filming the sequence legitimately does pay off — as it legitimately looks like the last section of the movie was filmed during a serious Nor’easter.
