I've been playing it slowly for the past few months after finally getting a modern GPU, and am going through the endings now, so my impressions are still fresh.
Overall I enjoyed the game, but it's possible to see that it could have been much better. There are still occasional immersion-breaking bugs like floating items and characters. Some systems are clearly leftovers of bigger plans, for example clothing that barely has any purpose other than roleplaying and taking pics of the character in photo mode. Gameplay can be pretty fun depending on your preferences and how you build the character, that was nice. I do agree that it's not particularly deep.
Story and writing is what people usually praise about CP2077 + PL, but after finishing the game I can say that I was occasionally baffled and disappointed. Some things were clearly not developed to full potential, possibly because of time/budget constraint. Quests mentioning some areas and characters that are involved, but you can't go and examine those. Some are pretty damn dumb if examined logically. Endings look pretty cool in isolation, but they contradict each other when compared. In pretty much every ending V is told that they're going to die, but reasons differ. Alt claims that the body was changed to that of Johnny, and the immune system would reject V (which is also nonsense, in the game's world an engram is data that can be written to a blank brain, why would data be rejected). In Arasaka endings we see that Saburo needs a body that is already genetically close to him, so he uses his son. Why not use a clone? This also contradicts what Alt says about nanites modifying the body. Arasaka-related characters also claim that V's body was damaged by the Relic, that's why even though the surgery was a success, they'll die. Tumors and DNA damage. But somehow if Johnny takes over the body he can continue to live in it no problemo.
A dark and depressing theme doesn't automatically make the story great, it still has to be logically coherent.
6-7 on IMDB is a pretty decent score, plenty of good movies in that range. If it's 5 and below it means it's right proper schlock.
