the problem with the films are that they just plays of the books! thats why most people don't like them as much, if the adore the books!
unfortunately im one of them! i love all the books and the films disappoint me! This is not just because of plot points that they tend to miss out but because the films don't have the type of essence the books have!
The big problem with OOTP(m) was that even though the film was dark...it just wasn't dark enough! There was extremely important plot points that they missed out! even though we all know it must be really difficult to have made a 956 page book into a 1hr and 30 min film and even though they left the most important things in, i just feel like the essence of it was lost in translation!
(SPOILER)Hopefully they might be able to cram all of the unsaid things they have left out of movies 1-5 in the 6th! from what i have seen and read HBP hasn't skirted over barely anything in this film! they have appeared to have left in ron and the chocolates, lavender has a part in this one too! even Marcus belby(although only a small part, which i think is good as the actor who played him tragically died in a stabbing in London a few months back)
Dobby and kreature have to be in this one even though i think that the could be easily left out! if they are ill never bad mouth the movies again!
