I only had a problem with the very obvious movement of making Laurel look good, after mistreating her for the majority of the season. There wasn't a bit of subtlety about it.
She finds incriminating evidence on Blood, because he's apparently stupid enough to write a press release a day before Moira's murder and left it on his office computer. Laurel is the one that gets Ollie out of his funk with a long speech, instead of talking some sense into him together with Diggle and Felicity. And then of course she happens to save Oliver, because he apparently forgot he had an explosive arrow in his quiver, or any sharp arrows for that matter. No, let's try to tie this super goon up with a bola arrow, which he'll immediately break through, and then actually engage into close combat, instead of immediately shooting him in the face.
