This box has six very good Harrison Ford films for a very good price, so for that I'd recommend it.
The DVDs of Witness, Patriot Games, and Clear and Present Danger are all the old DVD versions (even though the picture of Witness on the back of the box is a picture of the special edition DVD).
- Witness was recently remastered so there's a better DVD with more extras in circulation than the one that's in the box. (Although the old DVD - the one in the box - does have a short interview with director Weir that's not on the newer DVD, apparently.)
- Patriot Games and Clear and Present Danger received a modest special edition treatment a while ago, and I expected those to be in this box. The releases in the box don't have any extras besides the trailer.
There are plenty of subtitles on each DVD, but see the website 'DVD Compare' for all the info you need on that. It's not the same set of subtitles for each DVD though, it varies. (I should also add that there are also Dutch subtitles on the Clear and Present Danger DVD, which is not said on either DVD Compare or the box itself.)
I gave the box only 3 stars because I think we should have got the best available DVDs, but other than that, it's highly recommended.
