I didn't had the time to see the
Fate/stay night Unlimited Blade Works movie yet, but I'll review the limited Blu-ray contents:

The limited edition contains (in order from the photo):
- A box drawn by
Takeuchi Takashi.
- A folder containing a bromide and two film cuts.
- A color 20 pages mini-artbook.
- The blu-ray.
- A 160 pages mini genga artbook.
-Two alternate jackets drawn by
Ishihara Megumi (the
Rin one) and
Yamanaka Kotetsu (the
Saber one).

The folder containing a bromide of
Saber &
Rin and the two film cuts. The film cuts are two non-consecutive film frames. I got two pretty cool ones:
Rin in the rooftop...

...and a close up of
Archer.

The color mini artbook is a collection of pictures that appeared in several media (mostly magazines) to promote the movie.

Pictures that appeared at Animedia, Hobby Japan and Megami Magazine.

I find
Archer pose in the bottom left picture kinda disturbing...

The genga artbook contains key animation drawings for the movie.

Despite the small format (is the same size of a blu-ray case), is considerably thick being 160 pages long.
EDIT:
Finally I watched the movie.

As extras it includes several variations of the trailers, and as expected no subtitles.
Maybe is because the first blu-ray that I watched was the gorgeous
Evangelion 2.22, but I found the quality of the image average most of the time...

Except for some key scenes, the animation is only one step above a regular anime quality, and the the pace is so fast and leaves so much information behind that makes me think that this movie is incompressible as a stand alone without the background info from the VN.

The fighting scenes are fast paced and visually appealing, but if you watch closely most of the animation is sub-par... if you compare the picture above of
Rin fighting (that is not by any means the worst quality) with the scene of
Saber above, they seem like completely different movies.
