So i just bought the PS3 and with a lot of DVD's I am now in a process of determining which ones I might want to sell off and buy the Blu-Ray.

Though I have been told that some Blu-Ray discs are not all that much of an upgrade and have disappointed some people.

What kinds of movies have you found were not really worth the change. I am temted to get the Genesis Arc of Star Trek because I only have IV on DVD and 2,3,4 and 6 were the only ones I cared for. The First was boring and the 5th was pretyt bad. Even 3 wasn't that great. (Odd numbers for Trek). I read a tepid review of the picture quality of IV though and so now I'm wondering about it.

John Carpenter's The Thing I saw cheap which tempted me. I have the LD and the DVD and the VHS of that movie so may as well buy it yet again. Man Caprenter did well off me.
