Honestly, can you get any less creative than with this episode? It's a classic cry that the writers are at a solid block and can think of nothing else. There was absolutely no point to showing the viewers any of this besides to showcase the fact that Hiro and Peter are kicka-ss.
Obviously nothing in this future is good, you can tell who's still alive, and blah! I don't even know where to begin complaining about the mass of character changes! So many heroes are out of character it's sickening. There's only so many ways that a personality can change, no matter the grief, heartache, or shock that is experienced. This was not an accurate portrayal of the human emotional spectrum.
A horrible episode--let's hear it for something with a point!
