Endgame was actually pretty good, if you're a fan of the series.
It wrapped up the franchise as best they could after all these years.
(what other movies?)
If you do decide to watch it, get the DVD (like my roomate did).
I originally saw it in the theatre, and they cleaned up the ending a
little better on the DVD. Plus the extras are almost worth the cost
of the DVD in themselves.
The only thing that would have really made it better would have been to
include the Watcher files on the disk, but that would have probably taken
another DVD to fill it right.
Spook, you rant about the movies, but you don't sound like you ever watched the
series. It took a few twists along the way, but overall it paid a lot more respect
to the ideas that were played with in the original movie than any of the sequels
even thought about. (The last seasons got a little carried away, but that was just
a sign that it was time to move on...)
