Body and Soul: Very, very funny episode. The aliens of the week were fairly boring, but the real star of the episode was the Doctor in 7's body. Really a joy to watch! 7/10
According to Mike Sussman, Robert Picardo videotaped the 'possession' scenes so Jeri Ryan could study his voice and movement. It might be a good indication of cast relationships and willingness to help each other out. Ryan does really well showing the Doctor's delight at new experiences. And some lines are just hilarious: "You became sexually aroused in my body!"
Out-takes must have been a riot. I also give director Robert Duncan MacNeill a lot of credit for its success.
