Query: Better late than never!

I would give anything to have been exposed to the works of Carl Sagan during my childhood years. It's only within the last few months that I've rekindled my scientific flame, and I owe it all to two men: Carl Sagan and Neil deGrasse Tyson. Carl Sagan's naturally poetic prose combined with Neil deGrasse Tyson's intense passion combined to create a knockout punch which has finally set me in the right direction. I owe a great deal of gratitude to both of these men.Back on topic, however, considering the incredible speed at which science evolves, it is simply amazing that Cosmos is still relevant in this day and age. This fact alone gives Cosmos a five star rating! This discounts Carl Sagan's natural ability to inspire his audience, and if I could I'd give Cosmos an extra star or two.I'd continue, but there are already enough reviews of this outstanding product!Carry on.
