The products are excellent and the best versions you will find but my main issue is the way they released Captain Kronos. I bought the first original collectors set with 4K discs which I wont use, and would have bought a bluray only set. They then release a bluray only set minus a few things following the original selling out. Not a great idea by them as now I will wait till every collectors set sells out so I can get the bluray only sets and if there isint one the question will be asked, "If they did it once why didnt they do it it again?" I wish they hadn't released the separate set as it will cause problems in the future.
