Harry Potter 4: The Goblet of Fire.

This one is darker, more powerful and has a lot of sexual tensions. They grew up and Harry is being chased by some mysterious forces, powers of the past. It's exotic and plainly adventurous.

We also see how Harmoine, Ron and even Harry get noticed by others and we see them forming their own crushes. So now, Harry must not only fight the demons and monsters but also his heart.

Lord Voldemort will do everything to recover his power and the only way to do that is by using the only one he could not killed with his spell; Harry Potter.

In this movie we see a lot of action, spells, love, laughter, dance, parties and mainly the willpower to defeat evil. Harry Potter's worst nightmare comes to life in this part. One thing though, this story is too long to be squeezed in a two-hour movie, forcing the editors to cut a lot of information, making this a very fast paced moving story.

My opinion: Go see this one!
