Quite good movie but with one huge flaw (major spoiler)

Rating: 8/10 (12 June 2004)

I quite enjoyed the third Harry Potter movie. It was perhaps somewhat silly during the first 30 minutes, but the film grows darker and more interesting.
*****Major spoiler*****
I don't remember if this flaw is in the book also or just in the movie, but there is a great flaw when it comes to the time traveling. How can Harry Potter go back in time to save himself when he is already dead? He goes back in time AFTER the dementors has killed him. This makes no sense. Harry Potter dies together with Sirius fighting the dementors.
*****End of spoiler*****
The movie is well worth watching anyhow though.
