I actually watched all of the three movies. I was took by surprise because I think it was really good. I'm not fan of dialog movies but in that trilogy I didn't even mind it. I liked first two parts way more than the third. I actually think it shows the human nature of relationship/marriage quite well. It starts with doing crazy things, falling in love, enjoying nothing but the company of your partner, weird talks. Then in the second movie as years passed by you just see surface of that, both are more mature but you see the same idea behind it. And in the third one just whole other thing, marriage, problems etc. It was really well made, it's one of the rare movies when you think like 'hey, this shit is real'. Having said that I think acting (in all 3 parts) was absolutely brilliant.

I didn't watch it. I will be the last one.
Things change, people change. I actually watched some Westerns recently.
I didn't watch it 3D, so I don't know if my vote counts at all, but I didn't like it.
