I liked this episode. Fast paced action and the opening sequence was enough to set the tone for what was going to come.
Like sherlock said in his review, I think the episode could've spammed a "to be continued" right when Michael went back to the bank and it exploded.
So the second part would be around Michael going after the bank robbers in the tunnels. Maybe a little longer chase scene with the bikes and a bit more hard time knocking out the rest of the gang before finding the couple..
But overall, one of the best episodes, after the 2 part ones where the Dr. died. Cheers..
