I always enjoy checking out these animated DC/Marvel movies, just because I realise how little I know about the wider superhero universe and see them as a nice, handy crash course in familiarising myself with marginal, peripheral characters. What this film does is show you just how violent these stories can be, and how I REALLY don’t know much about these films. Essentially a story focused on The Flash and how he calls upon the rest of the Justice League to help him out when someone else starts running around with his powers causing all kinds of trouble, it really pulls back the curtain on how many players there are to draw from. Fun in its own right, but perhaps not a particularly useful entry point.
