Great CGI and music scores. Jared Leto really did well with his acting and the action sequences were decent.
The writing wasn't the best for me as it felt a little rushed and shallow. There were no details as how he found out he could walk in the sun, how Milo got to know which specific serum in the lab was the Vamp-serum, why the Doctor didn't contact Morbius after the first attack and so on.
There were too many gaps in the movie which could've been explored to add more depth and would've in turn, created an emotional connection between the movie goers and the characters - like in the case of Spider-Man No Way Home where people could understand Peter 1's pain and need for revenge after Aunt May's demise..
For someone looking for fast-paced, no need for a proper background story kind of movie, this is right up your alley.
It could've been way better if the screenplay and writing had more details.
