extended cut of underworld

[skylog]

i am contemplating picking up the underworld trilogy, i still can't decide. i have read mostly quite positive reviews here and in quite a few threads. i have some amazon GC money staring at me and it is either pick up the underworld trilogy or spread it across a few new and or used movies.

i have only seen the theatrical version of underworld and none of the trilogy on blu-ray. does the extra footage from the unrated/extended version of underworld add to the story?

lastly, looks as if it is as cheap as it has been for the trilogy. there would not be any obvious reason this would take a price drop anytime soon would there?

thanks
