Kotaku has a video review of the Arrow add-on game for Lego Batman 3. Stephen Amel is doing the voice acting, and there's some humorous narrating going on, in addition to what was in the introduction.

There may be some light spoilers if you've never watched the show, but if you're caught up you're ok. There are also a lot of revisionist spoilers that sound like they would have been fun to watch.
