I really liked the 4th film, but the rest never stuck with me. Maybe because the plot of the book is so suited to film: "Harry gets involved in a big three-part magical tournament. Bang bang bang. Climax." Maybe because the director put in a ton of romantic-comedy stuff that didn't NEED to be there, but it helped to make it slightly different from the books instead of trying and failing to adhere to the original narrative. Also everyone's acting improved.
I seriously have no recollection of the fifth movie, except for a lot of glass things falling down and breaking. Actually I think that scene was in the trailer.
Ya gotta tell everyone, Hatcher! Soylent green is PEOPLE!!
