I am constantly perplexed by villains.
As a fan of high-action fantasy and space opera, I demand villains that can operate on a grand scale — that can deliver conflict and challenge appropriate to my delusions of grandeur. However, as a slave to coherence and consistency, I demand villains whose motivations and actions can plausibly produce that level of challenge and conflict.
Now, I reject the notion that dumb action and plausible characters are mutually exclusive, as Hollywood and the AAA industry often seem to think. By all means, it’s a balance that’s hard to strike, but I think there’s rarely been as glorious a failure than the monstrous, enigmatic Reapers of the Mass Effect trilogy.
