Why The Flash CG Is So Bad - Is The VFX Unfinished?!

:0:0

Warning: This article contains SPOILERS for The Flash.
While The Flash is legitimately good, the CG effects work is at times terrible, and downright embarrassing at others. In fact, The Flash movie showing in theaters feels like an unfinished version - an advanced assembly cut with all the right pieces in place, but without the final gloss of DC’s expensive VFX department. Whisper it, but at times, The Flash's VFX is worse than Henry Cavill’s “invisible” mustache in Justice League.
Originally intended as a multiversal centerpiece of the original DCEU, The Flash has since become something of a free hit for Warner Bros. There are few stakes in-universe with the DCU reset incoming - and The Flash's ending does set that up - so it became more like a chance to mess about and tie off some loose arteries. In that light, and initially ignoring the issues behind the scenes, it’s great: a DCEU high point. But there’s no getting around the fact that The Flash has absolutely terrible CG effects work. And weirdly, some of might even be intentional.
The Flash’s CG Is Horrible

First, it’s important to acknowledge that not all the CG in The Flash is terrible. There are, in fact, some notable exceptions:

Supergirl’s flight is mostly handled well (partly because it seems to be the most practical)
The broad strokes of the final battles are impressive
The baby shower sequence has its moments
Keaton’s Batman is thankfully treated with the reverence and respect of not being ragdolled all over the place or undone by poor vehicle mechanics
The Speed Force looks cool

But those are the few high points of The Flash’s effects sequences. Counting off the worst elements is a bit like shooting fish in a barrel, but the real standout issues deserve a roll call of shame:

Ben Affleck’s big chase sequence is undone by poor rag doll physics and sloppiness
The shots of The Flash running at high speed are comically poor
Some of the sequences where Ezra Miller stars as both Barry Allens at once show their seams all too easily. They’re done with far less finesse than The Social Network’s Winklevoss twins
The Chrono Bowl sequences makes The Polar Express look cutting edge James Cameron VFX work
The hotly anticipated multiverse cameos sequence looks so bad it plays like comedy
Even the audio looping in action sequences is distractingly out of place
The Batman cameo at the end has a clearly CG Barry Allen whose face appears to be sliding off

If you found yourself wondering why everything looked so odd or why decisions to sign off on this version of The Flash, you absolutely will not be alone. The immediate conversations coming out of both The Flash reviews and reactions from screenings were dominated by confusion and criticism of the VFX work. Even the most positive of reactions are tempered by a range of caveats around the use of CG, the reanimation of dead actors (and the associated morality), and questions of whether The Flash's effects work is even finished. The level of how badly The Flash's VFX misses the mark is confusing until you start to pick a little at the surface level.
