I enjoyed playing the Red Alert series more than the original C&C series, due to the less serious storyline, light-hearted humorous videos, and fun/interesting missions.
For example, there's a mission in the Red Alert 2 Yuri's Revenge expansion where you have to 'liberate' Hollywood and you can enlist the help of Hollywood actor-like units, such as the Terminator, Rambo, Jurassic Park, Clint Eastwood, etc.
I hoping that Red Alert 3 will be just as fun as the original Red Alert and RA 2.
