Watched my blu ray copy last night, making this my second viewing having watched it at the cinema. In my initial review here I rated it 3rd out of the series, ahead of AOE and ROTF. I also said I heard it holds up better on the second viewing.
Well sadly I need to revise down my overall view of the movie. I now rank it below AOE because I'm happy to rewatch that whereas I liked this even less on the second viewing. I was bored for various parts of the film. Never felt any real excitement / emotion that I did in the other films (eg Dinobots hero sequence in AOE, Ironhide dying in DOTM, Autobots returning in DOTM, Optimus transforming for the first time in the original).
