They're all campy and the effects are dated, but they have a certain appeal. The best films in the series are the first three: Horror of Dracula, Brides of Dracula, and Dracula: Prince of Darkness. I think Brides of Dracula might be the best movie overall (interestingly enough, Lee's Dracula actually isn't in this one). Christopher Lee is best in Prince of Darkness. Peter Cushing honestly carries the entire franchise, even when the films are pretty bad (Dracula 1972, for example). There's never been a better Van Helsing!
