Just wanted to give a couple updates. Watched some new discs over the weekend.
Ready Player One 4K - Really pretty disc. There are a lot of shots that really take advantage of the HDR expanded palette. Atmos and surround effects are top notch. This will be a great demo disc
Gladiator 4K - I just had time to watch a few minutes here and there to see if it was worthy upgrade. Holy cow yes. The expanded color and detail in the armor and outfits is readily apparent. Didn't watch the whole battle in the beginning, but the DTS:X track is excellent with good use of overheads. The effects heavy shots (like entering Rome) are soft because they're simply upscaled, but overall WOW.
Seriously if you can do 4K both are really good. I was especially impressed with what they could do with Gladiator. RPO is popcorn/brain candy, but again very demo worthy fun.
Also watched MI:6 at the Flix:MX. Really good entry into the series. McQuarrie has cemented himself as his generations Frankenheimer with the chase shots. You will be pleasantly reminded of Ronin here. My only nitpick is the 3rd act felt like it needed tightening some. But really that's it.
For fun we watched MI:1 and boy does that Blu Ray need work. Looks almost upscaled with only DD 5.1 for sound. Wasn't planning on updating this one to 4K, but just might have to.
