I won't waste time trying to talk about the performances, because they are all great and powerful in their own way. Part I of the 'Deathly Hallows' is ultimately a strong build- up to what will be a triumphant, bittersweet finale for everybody. The franchise, like Harry Potter himself, has grown and matured as the years (and films) progress. With this film, we are slowly but surely bidding farewell to one of cinema's most successful and imaginative franchises.
It should be wise for people to at least watch the first six films in order before watching this one, if they haven't read the books already.
