I never got the first Spider-Man but since this came with my PS5 bundle here is my quick take
Pros:
The game was hella fun. Movement, combat, abilities. All good. The skill tree was kinda lame, but it didn't matter. You always had a choice to go in and fight or stealth. This game is hella easy for the most part because stealth is so good. Basically enemies never look up.
Cons:
This game was clearly meant to be just an expansion. It's not worth $50. Its apparently half the length of the first game... its very short. Its a shame too because the story, voice acting, and just the game as a whole is great. They should be charging $30 for this game not $50. Wait for it to go on discount. Also the last boss fight has a section that inexcusably frustrating. I don't like when they change the game worlds rules to make a boss more frustrating.
