I have now owned the Friends DVD collection for about a year and a half. I have probably seen every episode at least 5 times (some maybe 20 times!) and I am still not bored with it.
The Friends DVD collection consists of 10 seasons, each containing 3 DVD's. Both sides of the DVD have 4 episodes on them (with a few exceptions). There is a little summary of every episode on the DVD boxes, so you don't have to endlessly search for a certain episode you would like to see, which is extremely helpful!
This DVD collection is an absolute must for every true Friends-fan. Now I don't have to wait until 8.00 PM for friends to be on and have it being interrupted by commercials. I can watch every episode whenever I want and where I want (TV/computer)!
