Draco in Leather Pants: Richard B. Riddick. Central character, yes. Hero, no. Even as he's deepened and made more sympathetic, humanised even, as it becomes clear he admires honesty, bravery and honor, he's bent on his own survival. And none of that takes away from the fact that he is a murderer with serious mental issues, and he's only given more. His third film involves revenge.
Evil Is Sexy: Riddick and sexy are synonymous with each other, but the evil part depends on the viewer.
Alternative Character Interpretation: The Purifier's Secret Test of Character conversation with Vaako is obviously a Loyalty test. It's not clear if he's acting on the Lord Marshall's behalf to ensure that Vaako isn't plotting against him, or, given the Purifier's later actions, if he is feeling him out to see if he'd make a potential ally. Probably the latter, as the Purifier is earlier seen subverting the Lord Marshal by setting Riddick free from the Quasi-Dead after he realized Riddick is a fellow Furyan.
Memetic Mutation: The "EVERY MORNING I WAKE UP AND OPEN PALM SLAM A VHS INTO THE SLOT" copypasta. note The full text is: "EVERY MORNING I WAKE UP AND OPEN PALM SLAM A VHS INTO THE SLOT. ITíS CHRONICLES OF RIDDICK AND RIGHT THEN AND THERE I START DOING THE MOVES ALONGSIDE WITH THE MAIN CHARACTER, RIDDICK. I DO EVERY MOVE AND I DO EVERY MOVE HARD.

AND IVE LEARNED ALL THE LINES AND IVE LEARNED HOW TO MAKE MYSELF AND MY APARTMENT LESS LONELY BY SHOUTING EM ALL. 2 HOURS INCLUDING WIND DOWN EVERY MORNIng"
Count how many times Riddick takes his goggles off in dramatic moments in Chronicles. It's nearly impossible not to start giggling after a while. The odd part is, in Pitch Black, it's revealed that his night vision makes his eyes sensitive to light so he needs the goggles. In the sequel, this weakness is apparently gone since he whips them off every other scene, including one in which he gazes at explosions.
Kyra's "Shit! I hate not being the bad guys!" Yes, we get it. You're edgy.
They Wasted a Perfectly Good Plot: Riddick being at last captured and sent to a triple max prison on a hellhole planet where he reunites with a now jaded and cynical Jack would have made a fine enough plot on its own, without the frankly out of left field necros.
WTH, Casting Agency?: Dame Judi Dench? Really? More details rescued from that page: Chronicles made some fans wonder "What the hell is Judi Dench doing in this film?" Vin Diesel wanted her so much, he sent a humongous number of flowers and bouquets along with the scripts to convince her. She complied after they met and bonded over Dungeons & Dragons (they both play).
Justified as the role was designed specifically for her by Vin Diesel and David Twohy. Word of God on either the DVD commentary or the "extras" subtitle track.
