Is rick grimes dead in the last Ep of walking dead?? what do you think??

Not dead, and its a good move for a major character to die. Fitting that it is him as well.

TWD has been dying as a whole for the last 2 seasons. May be Rick dies might be a good emotional way to end it.

I am a big fan but well...

Yeah, but i think he's leaving TWD, besides it's an aweful death for a main character to die in a zombie bite anyway.
