For loyal, long-time viewers, this week's episode of Heroes was a trip down memory lane.

While it was fun to visit Odessa again, and to be reunited with old friends (Hi, Isaac!), it was also a painful reminder of just how great this series used to be. Homecoming? Isaac's painting? Save the Cheerleader, Save the World?

Ah, the good ol' days of tight, gripping storytelling.

Last night's installment, though, served a very important purpose: it shed light on Samuel's grand plan and it gave the season a direction. That's all we've asked for from Heroes: a sensible plot that builds momentum and brings characters together for a common cause. Again, think back to season one and the eventual meeting in NYC.

Only the most cynical critic would claim he isn't curious about what happens next on the show now. However, are we supposed to be sad that Mohinder was supposedly killed? Because I let out a cry of joy when I saw his body.
