I am fixing to be brutally honest, so here it comes......
As much love and respect the world had for this film back in the day it truthfully surprises me that such a shocking "4K" release was grotesquely whipped up and marketed at absolutely the lowest possible factors.
I have a Sony 4K TV, a Dolby Atmos system and a Samsung UHD player...for the most part every 4K that I have purchased I've been pleased with or blown away by; this "Ghostbusters 4K" is a disgusting example of bleeding money from people by taking advantage of a new thing. What do I mean, I mean slapping 4K on something that obviously is NOT!!!
Ugly UGLY grainy image, colors that run so bad it literally looks smeared, a very bizarre array of flashing in some sequences, I have seen videotape that is superior to this...just horrible...point blank...HORRIBLE!!!
I really don't know why people are saying that the 4K presentation is good...it isn't. This is a word of warning, this is a sickening ripoff!!!
To make excuses for it like it being an "old movie", that's completely silly, there is plenty of old releases on 4K that are choice gems, it simply boils down to how much effort is put into the work. For example, Night Of The Living Dead is a much older movie presented in black and white, the Criterion Collection made a phenomenal 4K release from that tiny film, it's actually one of the best 4K releases I have seen yet, age has nothing to do with it.
Instead of sending back the 4K disc I decided to do a comparison and purchased the regular Bluray release, the result...the Bluray is top notch, I have no complaints. In fact I would strongly recommend purchasing the one that I bought which contains both first and second films along with a collector's book. It has a "no ghost" sign on the front with the ghost holding out both hands, one hand he's holding up one finger and the other he's holding up two fingers.
The Bluray rocks, buy that set and you'll be very happy, if you buy this 4K you will not be.
Steer clear of this one, it is not what it says it is, it is a scam, I'm not sure why but it's strictly a false money grab. If you love the films then buy the Bluray. Heads up. This is a warning.
Thank God the Bluray exists. Thank God.
