Everyone who hasn't been sleeping under a rock for the last 10 years will know of the outstanding quality of the films in this box set, so it is not for me to review the movies here.
This box set, is however, slightly less impressive. The box itself is so-so at best; more or less average carboard box with a picture of QT's ugly mug on it.
The editions of Pulp Fiction and Jacky Brown are both great - loads of extras and loads of disks.
The Reservoir Dogs edition is the basic no-frills version. If you are into your fancy boxes and billions of hours of extras, then you might want to check out one of the various special editions that are available on Amazon at good prices. **Note: I notice that it says there are 6 disks included in this box set. When I got mine a couple of years ago there were only 5 - two each in Jackie Brown and Pulp Fiction and one in Reservoir Dogs. I can't say for sure but they may have upgraded the Reservoir Dogs version in this set.
If you like Special/Collectors/Limited/Whatever editions of your DVDs, buy them separately, that way you will be sure of getting the right editions.
If, on the other hand, you like boxes or are generally indiferent and only care about the movies, this box set is a not-bad deal.
Hope that helps.
