This manga is really stupid. In a good way I guess... There are some panels and scenes that are just so unbelievably dumb that you just can't help but laugh.
Overall I quite enjoyed the few key moments that this manga had to offer, all of which genuinely made me laugh. There's a scene where the main character Denji is literally in a life or death battle but decides it's time to go all out because he's motivated by his reward: getting to touch boobs for the 1st time in his life.
If you're here for a story or plot, you're not really going to get one. Chainsaw Man follows a sort of monster of the week format for the majority, with a lot of 'randomness' in the writing (or whatever you decide to call it).
In short, it's not a very compelling piece of storytelling but a great manga to turn your brain off and just enjoy the ride.
The art is pretty overhyped. Scenes are very chaotic, true to the nature of the piece, but very lacking in thought or composition. In between scenes and paneling are very weak or uninspired compared to the action panels.
This is not a manga I would ever give a second read unfortunately, but it is memorable to the point of enjoyment.
