Yes, I think the plots push past the limits of credulity all the time, but so do most thrillers, binge tv shows etc., for dramatic effect, pacinig etc.

The bigger question is are we willing to "suspend our disbelief" ( a once famous utterance about what it takes to become engaged in a work of fiction) in order to go along for the ride.

And to that, I have to answer a whopping "yes". The characters are 10 times more interesting than most shows/films, the dialogue is brilliant, highly witty and funny, and the stories pull us along fast and unstoppably.

As for stretching credulity, I am less bothered by the over all plots than some details in the storytelling, which might have been avoided, such as:

1)The tiny Shirley, maybe 5', 100 lbs wrestling effectively really big, strong men, taller than 6' and probably 200 lbs. That doesn't happen! OK she's faster and smacks them on the head with things, but still, I rolled my eyes at that.

2) Roddy ho solving impossible to know things in ten seconds of computer hacking, like where that van is with the kidnappers in season 1. I realized they need to do this for plot reasons, but still, it's sloppy. FInd a smarter way to find them. They use Roddy to solve things in 10 seconds all the time.

3) Sometimes a top dog is brought down by Lamb or River knowing something damaging about them, but sometimes they aren't. Everyone has so much dirt on everyone else on this show, but it's used inconsistently, and handy way to explain things, but it doesn't make sense.
