Most of the time, the books are better than the movie adaptations, which is the case here, but I have to say I am impressed with the adaptation. Harry Potter and the Half- Blood Prince is one of my favorites from the Harry Potter franchise. Plus, this clip with Professor Slughorn as the potion teacher makes this scene so much looser than Professor Snape, who’s very much more tense. Other than that, in the clip shows the potion class at work when Harry finds a book filled with notes and excels at the potion. To say the least, Professor Snape is very gifted when it comes to potions. Enjoy the magical clip!
