I absolutely loved this movie. I tried going in as blind as possible given it was going to be on Netflix anyway, all I knew there was Natalie Portman and others going into jungle and finding some weird shit, and I saw a glimpse in an ad of some kind of "purple wall". Besides that I only knew the early reception was good, so I figured I'd watch it the day it comes out, was really curious. Well, I was not disappointed in the slightest.
First of all, let's talk visuals. I've seen a fair amount of sci-fi and/or artistic movies in my life, but I don't think I've ever seen some of the styles, ideas, concepts this movie pulled off. Scene after scene I was in awe: the way the rainbow colours were refracted and gave everything a surreal halucination feel, the way the flowers and other plants evolved, the bear scene, all the area surrounding the lighthouse, the dude in the pool. From a visual standpoint, everything was top-notch, and while CGI wasn't always the best, the scenes that relied on static pieces like the plants worked incredibly well. A bit of suspension of disbelief is probably required all around, because it's unlikely that sudden genetic mix-ups would look so "beautiful" and clean, but of course you're making a movie, not an exposé on what Chernobyl radiations do to your body.
I also really enjoyed the movie's themes. Nothing was overly dramatized or explained, and I think that worked. I have not read the book, but from looking at the thread I see that in it the characters weren't named. I just don't think this would have translated particularly well into movie form: imagine one of them going missing and shouting "BIOLOGIIIIST" or "PSYCHOLOGIIIIST" to find her. Either way, very little background was given to any of them besides the names, so it all felt very mysterious still, and the fact they knew so little about each other was enough to doubt of each other's motives and identity when shit went down. Again, I've not read the book, but I feel that they've done a good job with this.
I also loved all the fairly little touches all around. The tattoo was very visibile of course, but there were the bruises also, and I enjoyed how the theme of self-destruction was handled. Maybe the whole "we drink, we smoke" line was a bit too on the nose and too literal when describing what self-destruction is, I prefer to view the movie as something of an internal self-destruction, not a physical one. Surely the movie and its themes took a bit to get real, but once it started going down, the movie was insanely gripping, the second half felt a lot shorter than the first one because I was in awe for most of the time. The ending, while slightly cliché, gives enough material to work in case they want to go for a sequel, albeit I'm reading that may not be a priority, plus I doubt the magic would work another time - but who knows?
Overall, this was a great movie, one I'm definitely going to rewatch in the future. While I enjoyed The Cloverfield Paradox to name another recent sci-fi flick, I felt they went too standard with the whole dimension mixing and shit. Here they went for a similar concept, different things merging into each other, but its realization was far more inventive and visionary, and the whole movie's visual identity is extremely unique. I expected some deep sci-fi shit thrown onto a Predator movie basically, what I got was far more interesting and thought-provoking, memorable and visually mesmerizing. Awesome movie.
