Hitchcock is Hitchcock. Things are not always what they seem. Hitchcock, and his favourite leading man, James Stewart once again take a central concept - a what if - and twists a tale around it.
I'm not sure I can identify with vertigo as much as I can with some of his other obsessions - the nosy neighbour who sees too much, the case of the mistaken identity, being falsely accused of sabotage, or the murderer who taunts his dinner guests with the murder weapons and hidden body. All these are more compelling - with a faster pace - and let his leading men be more dynamic than in this tale.
Still, Hitchcock remains the master storyteller, weaving a compelling tale together that has the power to entrall the audience with this film which still knocks the socks off the majority of modern films.
