Have seen it all before

Rating: 6/10 (21 October 2012)

I did not finish this movie, because I had approximately the same urge to see how this ended as I have to see whether the sun will get up in the mornings (and I don't live that far north).
In this review, I am going to try to predict what happens. If someone considers this as a spoiler (e.g. someone who has never seen a movie before in his/her life), don't read on after this.
First of all: The beginning was kind of original, and created hopes that this movie is something quite different. But then it started going downhill.
I turned off the movie during the 4-year anniversary dinner between John and his girlfriend. So far, I had seen how she pretends to be happy with her relationship, but that she probably feels that he is immature and doesn't have a good career. Also, her successful boss is always trying to get her to start a family with him.
Now, my guess is: She will probably leave John because she feels the relationship is going nowhere, and John will blame his teddy-bear Ted. So he will leave Ted in hope that this will bring his girlfriend back to him. But he has gotten it all wrong! It wasn't Ted who was the problem in the first place, but just the fact that John apparently didn't thrive for anything more in his life! The girlfriend realises that John has misunderstood, and at the same time, she also realises that her boss is actually not a nice person at all. And so the three of them get back together in the end and live happily ever after.
Am I right?
