Very good, not great, but not deserving the hate-on I see here.

Rating: 8/10 (11 May 2018)

I was ready to give this movie a 7/10, but after seeing so many triggered, sexually repressed so-called "anti-PC" reviewers, I gave it an extra point because, hey, mission accomplished, it seems. I guess it is art, because a lot of people got challenged.
For those of you crying "bestiality": Did you cry this for Star Trek, because where did Spock come from? What about the Worf and Jadzia Dax relationship? In the reboots, Uhura and Spock? What about Lord of the Rings? Aragorn is human and Arwen is an elf. Is cross-species romance and sex only okay if they look mostly like hot humans with pointy ears or brow ridges? The whole point was conferring personhood on the "Amphibian Man", which is how he's listed in the credits. Maybe think about the second word, rather than the first, eh? The point went so far over your head NORAD is tracking it.
Was the sex necessary? If you're a religious conservative and you harp on this topic for other movies, hey, I disagree with you, but I respect your opinion because at least it's coming from consistent ethos. Otherwise, put your faux morality away, Because I see that PornHub tab you have open in the incognito window (too late to close it now!). But yeah, the sex was kind of necessary, frankly. Steven Spielberg chickened out in "The Color Purple" so my mom could tell me (at the tender age of 18, as if I didn't know lesbianism existed) when Celie and Shug Avery were kissing she could use the insipid line "She's teaching her tenderness." (which makes me wonder if that were some "concerned parent" talking point going around then because over the years I've had two other friends tell me their mom said the EXACT same thing to them about that seen) which gave short shrift to the fact that in the book, Celie and Avery became same-sex lovers. Del Toro gives us NO wiggle room here to spin the story. Love it or hate it, Amphibian Man and Sally totally got it on. Not bagging on Spielberg (too much) here, there's a world of difference in tolerance between 1985 and 2017, and the Color Purple is a great movie overall.
Is this a great movie? In my opinion, no. It does have flaws, but plenty of others will gleefully break them down for you. There are some GOOD critical reviews here too, though it takes a bit of wading through the righteous indignation. But unless you're totally in love with the idea that God made humans in his image, I think you can find a lot to like in this movie.
