A great science-fiction police show with a message about racism, with the alien Newcomers here being the minority in place of blacks.
In the feature film, Matt Sikes was a vocal bigot. For the series, his character was toned down quite a bit. But he's still a non-racist in a racist's body.
Outwardly, he hates the Newcomers. He resents them moving in on human turf, is jealous of them doing well. He won't easily let himself befriend them or get close to them. But he defends them and stands up for them, often reluctantly, both as a cop and a human being.
