3/5 dics freezing
  by kebra (Canada)
I love these movies and although it may be true the first two years aren't as 'blu'ray-y' as I would've hoped I can get past it. They still look better than the regular dvd. The biggest problem I have is that they tend to freeze in certain sections and I have to fast forward and miss bits to get it to work again. I have the same problem with all five discs, straight out of the package. I have a new Sony Blu Ray player that works like a charm on every other disc so I know it's not the player that's the problem. I'm really disappointed.

5/5 Amazing

These movies are even better in blu ray. I saw things I missed in regular definition. I have these movies in regular, HD, and Blu Ray. I know, I am crazy.

I would recommend getting the movies on blu ray.

4/5 Good hold-over
  by Dan Wilson
Year 1 doesn't actually look that great for a blu-ray video but 2-5 are quite good. I say this is a good hold-over since the super ultimate special editions are being released starting next month, which one should probably pick up if they're going for the best picture and sound quality. Hopefully they will have improved the over-all visual aspect of year 1.

4/5 Blu-Ray Review
  by Walbert Matos
I'm not gonna review the movies but the blu-rays.

These blu rays are a mixed bag, movies 1 and 2 don't look as good as they should be on blu-ray but still look decent enough. But from movie #3 forward things change dramatically, the visuals are very good HD quality and improve with every subsequent movie. The audio follows the same pattern as with the visuals. About the special features I cannot say very much as I haven't owned the DVDs and I cannot compare.

If you are willing to forgo the lower quality of the first two movies and you love Harry Potter then this is a sure buy.

3/5 Great Goldbox... But worth replacing your DVD's?

QUALITY:

All/Most of the movies are great quality, really what you would expect from a blu-ray, although some of the movies (First 3) didn't give you the same kind of 'WOW' that the other blu-ray disks do, they just don't look as good as Iron Man for example. Regular DVD's (the first 3 at least that I can recall) on my PS3 which up-scales them looked almost, if not as good (pretty much, unless I'm old and going blind ... at 27).

SPECIAL FEATURES/ETC:

Right now there's nothing that stands out on these disks as a great feature to mention.

CONCLUSION:

If you already own some of the disks and want to buy the blu-ray to replace those, it may not be the best use of your money over buying simply the ones you're missing. However knowing that there are movies left to come, it may be best to wait for either the next box set, or further through the series. (not to say that if you get it for a good price, not to buy it ;))
