Not for me, much cheaper to rewatch it in the cinema. I have a cinema subscription so can watch films as many times as I want.
I see about 8 films a month I guess? And cinema costs £17/month. So cinema trip is effectively worth £2. Compare that to blu ray which is £15 to buy. Buying it for home viewing is way overpriced in my opinion, so I rarely buy blu rays any more. Sometimes buy second hand DVDs for 50p lol otherwise I only watch whats on Netflix. The value of films has plummeted for me - I mean for £25 each month (less than 2 blurays), I get as many films on Netflix at home as I want, and as many films in the cinema as I want. It is very difficult for me to now justify spending £10 or £15 on a movie.
