If it might help...I find INS to be sub-par, but TFF remains the only one I don't even have on DVD.
For the longest time I did not own TFF on DVD bvut I eventually bought it. It has some good moments in there and I do enjoy the movie. When I saw it in the theater evryone was laughing and having a good time. Today, much of the humor is cringe worthy. I wish they would do a directors cut and edit most of it out.
