I agree with whats been said so far, best to rent or borrow to see if its worth a purchase, unless you see a bargain of course. HMV have a preorder for X-Men 1,2,3 on blu-ray for £9.99 so i ordered that although not out until 21-4-09 that would be a steal. So far iv'e managed to get Spiderman trilogy for £15 and Matrix trilogy for £15 also Starship troopers trilogy for £17.95, i consider these to be good buy's as i will play them many times. I find sometimes shops have silly preorder prices where you can get a bargain, or look for 2 for £20 at Asda or 3 for 2 at Play or Amazon. Just shop around and you can pick them up for the same price as new released dvd's. As for pq and sound Spiderman much more depth and hd sound, Matrix was good as well but Starship troopers no improvement at all. Most blockbuster titles will be a little more and wont yet feature in the 3 for 2 section so be patient and rent them pick them up when they do drop, same with xbox games and ps3 currently paying £17.99-19.99 for big titles like res 2 and little big planet, along with many 360 games, friends fret when i tell them what i paid.
