I feel like what I'm about to say may be along the lines of what Mike was refraining from saying, but I feel compelled to offer some sort of advice, so...
>I can watch most Japanese television shows and movies without subtitles,
>but I am really getting killed with this N2.
I'm not trying to be mean, but if you're getting "killed" by the N2 listening section, I'm very skeptical of how well you are actually understanding these TV shows and movies you're watching sans subtitles. It's very easy to fall into the trap of hearing a few words and grammatical structures you know and feel like you're getting the gist of things, while in reality many of the finer points are going in one ear and out the other.
When I was around N2 level and actively trying to improve my listening comprehension, I would often take dramas and TV shows and whatnot and transcribe them, as a way to test myself to make sure I was actually processing and understanding everything I heard. If nothing else, it's good practice, and it might help you identify weaknesses you didn't know you had.
