Yeah the Patil twins being in the same house bugged me too. It was great for the most part. Things I missed was Hermione and Ron helping Harry learn jinxs, the actual QWC, Mrs. Wealsey, Harry naming the DEs at the end, giving the the twins the 1000 galleons and other stuff. Things I liked dragon scene, Neville shining, the Drumstang entrance, the Yule. The only thing I really disliked was too much Dumbledore. They gave most of Ludo's parts to Dumbledore and it didn't quite work for me.
