Also watched this and had the same thoughts, great idea and style (reminded me of Gattaca) but just seemed to be missing something.Upside Down
Beautifully made, good visual, awesome idea but something lacking in the script. in Time with Justin Timberlake has a similar idea with 2 worlds (poor and rich) but executed that bit better.
Trollhunter - 8/10
Enjoyed it far more than I expected to.
Also saw Argo last night, thought it was orite wasn't blown away by it though
7/10 I guess, would watch again just to make sure I 'got' all of it
Battleship, saw it at the cinema when It was released but just watched it again. The visuals are pretty special but it's all just too silly. 6/10
Skyline - 4/10, that might be too generous actually.
Visually it was quite nice, the special effects/CGI seemed quite good but the storyline was flat as a pancake, the characters were unlikeable and it didn't really build up into anything.
