Spoiler space ...
I was annoyed that, after going to great lengths to explain how time travel
isn't really possible and these are actually trips to alternate timelines ...
the whole plot hinges on "clues" sent forward in time from our own past by
the people stranded there. And again at the end, when, back in the present,
the heroes visit the grave of their friend who remained behind.
Except, according to Crichton's explanation of how this all worked, that was
all on another Earth! So how did the clues and his grave get to ours?
