>The FIRST EVER MAINSTREAM 40K movie might be the first Tyrannic war
I think that's a cool way to introduce people to 40k, nids are the easiest enemy faction for normies to get while learning about the Imperium. Most imporantly however, is that having tyranids be centre stage is that it appeals to women ,which for the bean counters means they can appeal to twice as many viewers.
