The Half Blood prince, the sixth and latest adaptation from Harry Potter's books in my opinion was the lamest and most dissapointing movie of all six. At least the previous five has tons of action, adventure and humor. But this one is two hours and a half of the same boredome story. It is a flat plot that never advances and the lame excuse or romance make the film ridiculously cheesy. The very few of special effects that the movie has were very good. The cast were good but their performances in comparison to the previous movies were a little weak, I don't know but I never felt any emotion in them. The only ones that were convincing enough wer Alan Rickman as Snape, Michael Gambon as Dumbledore and the very little appearance of Helena Bonham Carter. In conclusion, Harry Potter and the Half Blood Prince for me is the biggest dissapointment of the summer and even the year.
