AC's classic! Will SyFy get it right? Here's the trailer:

It looks okay. I might check it out since it's just a miniseries, but for some reason "Aliens land and want to help Earth but have a hidden agenda" just doesn't really interest me all that much.
To be clear, Arthur C. Clarke's original story was written in 1953. So, if it seems cliche to you, it may help to realize that this is the original from which the cliche came.
And if I remember there is a twist. That simplified plot isn't all there is to it. And no, they were not invisible.
The aliens didn't show themselves until well after the initial meeting, if I remember correctly, because they looked like Devils.
I thought this was a weak point of the story. I don't see how it advances the main story, which I understood to be a kind of transcendence.
I thought the strong points were the notes of loss together with a largely unexplained transition.
