The Ending was...
(SPOILER)
Pretty fun considering if made me immediately think about the ending to HEAT. De Niro chasing after Pacino and then killing him, he got his revenge.
Anyway, i gave this movie a 7/10. Not a bad film and although i had a feeling there would be a twist, i didn't think it was Pacino the whole time.
Descent movie with 2 great legendary actors!
