Paul Walker was not only an handsome guy and a excellent actor, he was also one of the good guys of Hollywood, and there's not a lot of them around anymore.
Only after he passed away have stories come out about him trying to lead a normal life the best he could, despite his fame, and he'd be more than happy to chat to fans, especially about cars and racing while he was just sat having a coffee, and he was just an all round nice guy who is sorely missed.
I've not heard one other actor or director have one bad word to say against him, and alive or dead, that's pretty unique, especially in the movie industry.
