Harry Potter the third

Sucks! No gd, maybe i have a retarded mind, i simply do not understand what the movie is all about!! Waste my $6.50 and my time and energy!! Seeing some silly fools sneaking into a tree,then 3 people turn into animals wadever!! The movie went blank screen for nearly 5 times!The next scene will then be "harry r u Ok?" I want to watch the Mean Girls after watching the trailers, i bet it must be a funny movie!!
