Lets get the bad out of the way. The villian is still not a real threat and I find it terrible that he can give Batman such a hard time.
But the good was..well, good.
Alfred continued to be a big help by dressing as Batman when Bruce was busy. The fight "words" kept with the theme of the episode. Also, when the boat is first shown, they did a sustained camera shot from the upper part of the deck to the lower section. While the boat was clearly a staged prop, that little bit of camera work was nice.
The weekly moll, Maid Marilyn was an odd one. When a moll decides to dump the bad guy to help Batman, they usually have a reason. But not her, she just gives Batman and Robin swords for no reason. She was safely away from the fighting and did not seem angry at the Archer. Def not angry enough to betray him.
Overall...it was ok, but the Archer is no Joker or Riddler.
