Are his movies worth

Citizen Kane is a must-see for anyone who is a film fan. The first time you watch it you may be underwhelmed due to its immense reputation which sets unrealistically high expectations, but it's one that should grow on you over time. It's certainly a good film. I've watched it twice and I'm sure I'll eventually buy it on Blu-Ray.

Touch of Evil is also a good noir film. It features excellent performances from Charlton Heston and Orson.

I have not seen them, but I've also heard that The Magnificent Ambersons and Chimes at Midnight are very good as well.

Yes. they are definitely worth watching.

Definitely watch Citizen Kane. Some of the camera tricks are just unbelievable. I haven't bothered to watch his other flicks, they were all box office failures but I hear they're still pretty good. Also, they say he peaked early which I definitely agree with.

Citizen Kane is the only one worth watching. The rest was terrible, especially The Stranger.
