I have enjoyed every new detective this show has thrown at us, except Neville Parker. He's just plain pathetic and annoying with no redeeming qualities. The only way a character that is this annoying can be acceptible is if they are so overwhelmingly brilliant that it can be excused (I.e. Sherlock). He's not. He's both annoying and mediocre. He needs to go.
The ONE thing this show has that keeps it going season after season is the joy of the island life and that laid back feel. Neville Parker changes the whole tone of the show without any other powerful character to keep it loose and fun and it makes me want a can of bug spray rather than a rum punch.
