Watched the 2D Blu-ray last night and later skimmed through the 3D br.
I originally saw it during it's theatrical release in IMAX 3D and visually, the movie is extremely impressive. The Blu-ray transfer perfectly replicates the beautiful, saturated colors and the intricate details of the production design are a feast for the eye. Probably one of the overall best looking Blu-ray releases I've seen in some time. The 3D disc on my Panny 65VT50 looks amazing - one of the best 3D Blu-rays I've yet seen.
The audio is powerful and fully exploits either the 5.1 or 7.1 DTS-MA surround soundtrack choices, but has a bit of a muddy low end, imo. It actually was a bit of a fatiguing listen by about 2/3rds through.
The extras are pretty much wrapped into a multi-chaptered, approx 10 minute per featurette "Focus Points" which can be played individually or as a whole 1 1/2 hour program program. The 4 deleted scenes run a total of less than 5 minutes.
The movie itself is a mixed bag. As put forth by Del Toro, it's supposed to be a homage to old school Japanese giant monster/mecha films and at times wildly succeeds. However, the overall plot (it seems more like part 3 of a trilogy), some rather dumb situations and predictable, flat one-dimensional lead characters significantly impact the film.
My two biggest beefs with this film is the fact all the major monster vs mecha fights are staged in rainy, night time settings or underwater shrouded in the dark. For the centerpiece battle in Hong Kong surrounded by the primary neon colors of the city, it mostly works but else ware, it's frustrating to watch.
The other and imo, biggest problem with this film is the lazy, forgettable music score. Something that many fans don't realize that's a key part of the classic Japanese giant monster films, especially from the 50's through the early 70's was the often epic and exotic soundtrack scores, best exemplified by the work of Toho Studio's Akira Ifukube in films like "Godzilla," "Mothra vs Godzilla" and "Atragon." Pacific Rim's music is mostly anonymous sounding techno hard rock with almost no memorable themes (there's one 2-note bit heard during the beginning of the pre-credits battle that comes and goes never to be heard again).
For comparison, the last big gasp of the giant monster "Kaiju" genre, 1990's Japanese Gamera film trilogy, especially the last film "Gamera 3 Awakening of Irys" produced at a tiny fraction of Pacific Rim's gigantic budget pushed and expanded the boundaries of this kind of film in intelligent and exciting ways that Pacific Rim unfortunately fails to do.
Still, for it's flaws, Pacific Rim *is* an entertaining and technically beautiful film presented on Blu-ray and well worth checking out. And perhaps best of all, there's none of the obnoxious, smug humor and already dated quick cut shakey-cam photography that makes any of the Transformer's movies so difficult to stomach.
