If you listen to it, you'll understand why it received this score. To elaborate further: The detailed explanations regarding specific features and operations are very lacking. While having a syllabus is better than not having one, the explanations within it are also insufficient. It feels like nothing more than identifying a feature and copy-pasting code. With how much AI has advanced lately, you can get great results just by pasting official documentation into an AI to learn how to use a framework. In my opinion, this style of lecture is going to have a hard time surviving now. At the very least, I believe we are in an era where lectures should explain both the terminology and the underlying principles of how things work, and development courses need to be designed for the student's convenience. This is essentially a "quick taste" introductory course, yet I find the cost to be expensive compared to other Next.js lectures. It was a very disappointing lecture. During the explanations, saying things like "this feature is so great," or telling us to ask the free version of AI while simultaneously saying "don't trust AI"... I'm not so sure about all that. ^^;; I originally gave it 2 stars, but I'll raise it to 3 because the examples don't break significantly. (There are some parts that don't work because updates are occasionally lagging, but they are issues you can solve yourself if you've been paying attention to the lecture.)
