I haven't purchased this from MightyApe, but I do have all 3 seasons on DVD (including the cut down Bluray versions from Germany). This is, without a doubt, one of the best of the best BBC shows of all time. John Luther is a darker version of Sherlock Holmes. He struggles with his demons yet is extremely intellectual. I also read the book The Calling that was written by Neil Cross who also created and wrote the show. It's a prequel to the first season (the books ending mirrors the beginning of the show) and gives deeper insight to the characters that you grow to love in Luther… Even though Luther himself is extremely likeable from the very first scene.
This is a dark, brilliant and amazing show who I would recommend to anyone that enjoys the more ‘drama-ish’ shows. It does have some twisted stories and characters in it, so it's not exactly for the faint of heart. MightyApe has a list of the awards the series has received and I'll be the first one to say the show deserved EVERY one. I cannot recommend this show enough.
