Query: don't get this

the book was okay, but Chris columbus wrecked it, especially with the corny spider scene. the actors were mainly pretty wooden, especially radcliffe, who said his lines with no emotion, nothing to make it believable. The last one was made watchable only by Coltrane but in this one he plays a much smaller role. The comic relief void left by his absence is filled by Kenneth Branagh, who gives a fine preformance as harry's new teacher but nothing special. Finally, the worst thing about this film is the ending, a scene where everyone in hogwarts is happy and hagrid comes and gives them all a big hug. This sickly sweet scene is not in the book. if you must have this then save some money and rent it.
