Maybe I'm looking at it from a different direction, but thought the Amanda death was terrible for other reasons. As in, we didn't even realize she had died until later, when it was explained what was going on, and then you just sorta figure out that she really DID die, and that was it, no further mention. Wasn't really any emotion or sense of loss, as you didn't realize that was IT until later on, and then she didn't come up again.
Felt like it needed SOMETHING more at the time to highlight the danger of what was going on. She just went to explore it, and end of story. Didn't need a long drawn out death scene, but didn't really have the impact on me that I felt it deserved.
A lot of who lived and who died coming out of the anomaly felt kinda abritrary in this one. Tough when you're dealing with Q and essentially magic, I guess, but lessens the impact of the deaths when you just give some a do-over at random by the end.
