I knew I was getting this set from the moment I saw the first images of this line. I got it as soon as it showed up at my LEGO store, and I absolutely loved it. The only thing that would have made this line absolutely outstanding would have been if the pieces were printed instead of stickered, but it also probably would have jacked up the prices, so I guess we have to make a compromise somewhere. It was hard for me to put the set down and not spend my night going around my house, abducting all of my minifigs (Series 4 biohazard was particularly fun, though).
I did get an extra antenna with my set, which was nice. They can be fragile pieces, but consequently, I got the Alien Avenger (6975) when I was a kid, which has the same antenna pieces, and I was so particularly fond of that set that I managed to hold onto those pieces (surviving multiple moves and my Dark Ages) and still have them completely intact. Would they survive at the bottom of a bin of LEGO pieces? Probably not, but they are a cool enough piece (at least to me) that they would be worth safe-guarding.
