The Flash Review: 6 Ups & 4 Downs

2. The Fan Service Eventually Goes Too Far

Though The Flash has been designed to deliver laser-guided DC fan service galore, often to hugely crowd-pleasing ends, there's certainly a moment - at least one moment, even - where it goes too far for its own good.

Without going into too much detail, Warner Bros. has relied extensively on VFX to make this as jam-packed with legacy DC characters as possible, and there comes a point where it becomes more ghoulish than fun.

Beyond some of the genuinely surprising flesh-and-blood cameos, some long-dead DC actors have also been brought back into the fold via CGI, in ways that aren't only ethically questionable - they're visually revolting.

Even accepting the argument that the estate of those in question signed off on their likenesses being used here, the moment-to-moment fidelity of these images is a far cry from, say, Moff Tarkin in Rogue One or Egon in Ghostbusters: Afterlife, neither of which were totally persuasive themselves.

Ultimately the decision to go this route in The Flash has a certain "please clap!" desperation to it, no matter that it's the most hollow, soulless brand of fan service imaginable.
