I like Regan but it does have a different feel and pace to what eventually became The Sweeney and how the Regan character interacted within the series. Regan and Carter's relationship (and eventual friendship) isn't as obvious in Regan and in some respects there is a more tense undercurrent here. Haskins also doesn't have the mutual respect for Regan he has in the series which mellows considerably and is on the point of kicking him off the squad too. Also the scenes and acting styles are a lot more paused and stop start than in an average Sweeney episode and feels more like a bridge between Special Branch surprising as IKM didn't sound very complimentary to it in later years. Overall it's a great pilot of a greater TV series.
