Best story is
Snow Day because it had EVERYTHING and EVERYONE on the cast got some great moments. Well, not Lindsay, but she's my least fave character so I don't care.
Other ones which really stood out for me are -
Blink - the dark storyline, the insight into what makes Mac tick, the Ground Zero scene (still incredible!), and because it's the first proper CSI NY ep. I can *feel* the city in this episode, something the show's kind of lost lately.
All Access- yeah, Stella was the victim, and there were problems with the storyline, but Melina just knocked this ep outta the park. She really showed us a very different side to Stella.
Right Next Door - for the Stella storyline.
Officer Blue - the Mac/Jane scene, the Mac/Stella fight, Mac being all pissy at the end. The pizza parlour thing with Aiden's a great touch too.
Heroes - seeing all the team's reactions to Aiden's death, seeing DJ Pratt finally get caught, and the really nice scenes at the end, first Mac with the Marine's 'widow' and then the scene with the whole team at the bar at the end.
Child's Play for the Danny Drama. And Jacqueline Pinol as Rikki - AMAZING!
Consequences for the Mac/Flack Drama. Also, Kyle Gallner is wonderful in this ep.
Down the Rabbit Hole for Adam's...Adam-ness and geeking out. That truly was AJ's episode, he needs more!
And Here's to You Mrs Azrael - I liked this one because the people in the case weren't wealthy, they were just normal. I liked the darkness of the story. I loved the bit of insight we got into Hawkes' past.
Those are my favourite episodes. I have a lot which I like just for certain Mac scenes, but the ones I chose were either particularly good Mac stories, or good stories for the other characters, or just damn good plots.
