Missed Opportunity at the End
The scene between Kate Lloyd and Sam Carter-Thing was fairly interesting in the sense where you catch a glimpse of the Thing being more or less cornerned and exposed with its guise down.
What a missed opportunity. I think they should have drawn out the the dialog in the scene longer where, her being in the scientific community maybe she'd have a few more questions for this being since its the first sentient off world species humans have encountered? Its not like it was going anywhere with a flamethrower pointed at it.
