The film’s convoluted parallel plot adds almost nothing to the impact of the storytelling, other than to make it feel muddled.

For a film about a very fast man, the narrative is slow at times. The tacky CGI and video game artistry make the experience less immersive too.

For 2/3 of The Flash -- and it's too long -- it's kind of fun... in the last sections it becomes slightly video game-ish.

Its biggest strengths are treated as a relative afterthought, stuck in a time when movies like this could get away with the bare minimum.
