Just Boardwalk Empire. Aside from a few minor issues (no proper resolution for Rothstein, skipping significant historical moments both before and during the season), this season of Boardwalk Empire is firing with all cylinders. Sons of Anarchy is, well, stalled out. When the second shoe that's been hanging in the air all season finally drops, things might finally get interesting, but right now, meh (aside the last five minutes of the last episode).
I've been loving the final season of Boardwalk Empire. Sons of Anarchy I stopped watching in season four or five because I didn't think it was very good at all.
