A perfect way to begin the finale and the smoothest editing ever
16 May 2009 | by (France) – See all my reviews

How the hell will Michael do this time to save the day ? That's the question that haunted millions of fans around the world after watching the previous episode. Of course this one began to answer the question and it was really interesting to see our favorite breaker struggling. Moreover as expected he teamed up with Mahone but as usual things didn't go as planned and many twisted events occurred. The decisions they had to make reminded of Batman Foverer when the dark knight got trapped by Riddler, asking him to choose between Robin and Chase. Beside that thrilling story the direction felt really solid and all characters had the scenes they deserved. The true nature of the mother was revealed during a conversation with Lincoln. The actress overall performance is quite good and in this episode she managed to confirm her talent. It's fascinating to see how her profile contrasts with her clothing line, looking as innocent and pure as a white dove. Sara also got the honor of hearing T-Bag's thoughts on life and love. Of course it was both disturbing and funny but the greatest thing was that the writer referenced past events that should appeal to long time fans. Some minutes were also dedicated to covering the Self arc but it was only a minor one compared to the others. Last but not least beside the usual McGyver voodoo, which was really welcome this time and not over the top, there were some major changes in the casting. An other reason for the fans not to miss this great first part of the finale.
