Short answer: The game is fun with immersive graphics and gameplay.
Long play: First and foremost, the game is great, especially if you have a high end device. It changed the mobile gaming industry in many ways. But that is also it's flaw. "If you have a high end device". To be fair you can still have fun if you're into competitive gaming. But if you are then there is a bad news for you. With subsequent updates, there is a chance that if you don't have a shiny SD 855 or a higher than iPhone 8, chances are you might run into performance issues. Also the devs seem to running out of content. The addition of "wow" mode was a good ddecision to allow the community members to add some cool new mini games, but other than that, the dev do not seem to be putting any effort into making the game more optimized and seem to focusing on 'more content' rather than 'quality content'. There is also this "pay to win" system for crates and skins where luck essentially mean "how much worthless the item is or how much of a generous mood are the devs having at that day". There is no way to use your skills to earn atleast comparable items, so unless you have deep pockets you are willing to empty on those rigged items, you are not gonna get anything most likely. Then there are some game modes that especially I enjoyed, so maybe I come out as biased but I believe that the devs should have kept them instead of removing them. The addition of special abilities in ranked classic modes was a great choice. And i am glad it's here to stay.
If you have made it to the end of my review on this game and if by extreme luck (for me) you happen to be a PUBGm dev, I have a few suggestions. Add some sort of 'X-suit" and "Upgradeable" comparable item in achievements that players can earn using their skills but are aalready maxed out so that they do not spend money but instead their skills. Just give them some of the basic features atleast. Make it harder maybe, like "reach conqueror for 3 consecutive seasons" or something like that so that skilled players who don't have deep pockets can both have sòmething to show for. It not only will be rewarding for the players but will also leave a great mark of devs, that the devs care about all of ttheir players and not just those with bigs bucks to spend.
