It's always awkward to walk out of a movie theatre and realize the last two hours were only put in your way to help you waste time. Usually I don't have that kind of sensation (or lack there of). Usually I can understand, at least from a concept basis, why the filmmaker thought their movie would be worth our time. Any kind of movie can affect our lives. Unfortunately, Transcendence neither seems to care or want to.
I really am not one for spoilers, but the only way I feel I can accurately assess this movie is by walking through the awkwardness that was the final moments... if you really intend to go see this movie and think there is any chance you might enjoy it, stop reading now.
Then Paul Bettany rambles into a very confusing and poorly written monologue about the garden the two of them made together... and would (I guess) live in forever (??). A drop of water falls... cleans up the mucky water... and the movie just... ends. It's one of those endings that leaves you slack jawed because it literally gives you nothing... not even something to consider as you walk out in silence and drive home... in silence. Because honestly there's nothing to pull from this movie for future conversations except the old, "Remember that movie Transcendence?" To which I would reply, "No."
