I'm an American who binge watched 3 seasons in French w/subtitles before I even found out they had dubbed it in English. I watched 1 of the episodes that was dubbed in English & I actually prefer it in it's original French w/subtitles. It loses something w/the voice actors they chose for the dub.
The premise is awesome bc it's actually kinda spot on. I've seen things that police/prosecutors have missed that are obvious to me (& are kinda common sense), that should've been picked up by someone along the way. Doesn't matter who.
The characters are fun & work together. Of course you're going to gave the push/pull at first, due to the egos being bruised. Viewers will enjoy watching the relationships of the unit grow.
Of course there's not only the weekly murders to solve, but there's also character backstory, which of course brings it's own drama, misunderstandings, warmth, friendship, and love.
You have fun, quirky characters, along with the prerequisite stick in the mud characters. You have cute kids and some pets. All blended together to make a great cast.
Give this little show a watch. I recommend this wholeheartedly. The American version is also cute, but don't discount the ORIGINAL. It's the best one.
