The picture & sound quality is pretty poor. Never mind a BluRay or even a DVD, I feel like I'm just watching an old VHS. At the beginning in the credits, you can clearly see lines going behind the writing all the way across the screen. The picture is as grainy as ever, and all the little film dust and flashes are there as before...
Fair enough if they couldn't spend millions restoring an old show, but they could at least have made an effort to do SOMETHING or at least not say it's fully restored when to me this looks no better than a VHS. The fact it says at the back "FULLY RESTORED UNCUT ORIGINAL FEATURE" is a blatant lie and making people believe they're buying something in great quality when it's not!
On the + side, I should say that there is a very nice photo gallery containing dozens and dozens of pics (albeit completely in the wrong order and some pics showing twice), including some stills I've never seen before. But that's it: no documentary, no other languages, really nothing else at all you'd expect from a BluRay release...
In summary, don't waste your money and buy the DVD version instead (or just keep with the Seasons 1-3 Series DVD boxed set as this Movie version is just an edited version of the Pilot episode)
