The lecture content is good, but you should be aware that it is not very beginner-friendly. There are some parts where you have to fix the code yourself, or the content jumps around quite a bit. For someone who has already studied Spring Boot to some extent, skipping the detailed content is fine, which aligns with the purpose of a portfolio lecture. However, having to fix the code yourself from time to time was a bit of a time-waster and disappointing. (The intermediate steps in the code are not in the materials, and the lecture only shows parts of it, which is quite disappointing.) Since most people taking this lecture have already studied Spring Boot to some extent, skipping intermediate steps isn't a big problem, but the lack of materials is why I'm giving it 4 stars.
