The sixth installment in the "Harry Potter" franchise also topped this year's biggest hit, "Transformers: Revenge of the Fallen," which pulled in $16 million from midnight screenings on its first day in June.
"Half-Blood Prince" focuses more on the developing romantic relationships between the characters, and less so on the action and adventure. And even though it is more grounded in reality and less fanciful than previous installments, it is still spellbounding.
Mixed feeling were aired after watching this movie. Harry Potter and the Half Blood Prince is very interesting and the best Harry Potter film so far for some while others thought that it was one of those films that you could have easily gone to sleep in
