I actually liked Alexander, especially the soundtrack (it's by Vangelis who doesn't do many tracks but is one of my fav. composers - see his other work in '1492 - Conquest of Paradise' and 'Blade Runner' and you'll know what I mean).
The other 2 movies are also very good. Overall, quite a neat package and the quality on Blu-ray is exceptional. A quick tip: buy this pack from Amazon US as it will work out cheaper even with the shipping costs. I got mine for a bargain - about £12.50 including delivery!
