Thanks for response Anchorhead.
You obviously have not made the upgrade to blu-ray in regards to your home movie library.If you ever do you'll have to own the directors's cut of Alien (featured seamlessly branched alongside the theatrical cut) and in order to get the 90's director's (approximated) cut of Blade Runner you'll have to buy the uber-set.
That's not a bad thing though. Alien looks great and I love the little introduction Scott gives the film. Like I mentioned earlier the director's cut is harmless, for me it's more a curiosity to see one significant deleted scene reinserted and some other minor scenes/shots.
Also since you watched Blade Runner so many times in the theatre back in the day having the theatrical cut to revisit every now and then could be pretty cool. The movie also looks amazing. I'm 90's director's cut fan myself, but I'll also watch the final cut, I don't notice the minor differences.
