Is Crackle Really Free, Safe and Legal to Use

I've just installed Crackle for my Samsung TV & Xbox 360, and wonder if it's really free of charge?

I have used Crackle for several days. It seems to be a totally free movie streaming app, only with some constant commercial ads. Is it really free to watch all available movies, TV shows etc.? If so, whether the streaming and watching service is safe and legal to use? How to remove advertising for smoother video watching? Morever, what's the difference between registered user and unregistered one?
