  - Doesn't it seem as if Barclay is staying conscious for a long time through his process of molecular deconstruction?
  - The away team finds a Lieutenant Kelly dead and covered with second and third degree burns, on the USS Yosemite. Crusher states that he did not die from the burns. But the episode never says what Lieutenant Kelly did die from.
  - It appears the crew of the Yosemite ran their plasma tests with the comtainer still on the transporter pad. Don't they have a lab for this type of activity? This is a science vessel.
  - If the worms in the transporter are members of Starfleet, aren't they behaving rather strange? One did bite Barclay's arm.
  - For the past five seasons, the doors adjacent to the center island in Main Engineering have led to turbolifts. In this episode, Barclay opens this same door and the turbolift is gone! Now it's some kind of auxiliary engine room.
  - When did O'Brien get demoted? At some point he got busted back down to ensign! He takes a direct order from Barclay. I thought both Barclay and O'Brien were lieutenants. However, in this episode, O'Brien is wearing only one black-centered pip.
  - After discovering the life forms in Barclay's arm, Crusher gives him an armband monitoring device. She says it will tell her if "there is the slightest sign" of the life forms increasing in his system. Later, in Engineering, Barclay collapses as a blue glow erupts from both arms and his neck. Oddly enough, the monitoring device attached to his arm doesn't seem to inform Crusher of this development.

  I'm fond of this episode, like I am of most Barclay episodes, but the premise here is borderline ridiculous. I don't mean the existence of the matter/energy microbes in the plasma stream. I don't even mean the idea of the crew members trapped in the energy stream.
  
  But how does Barclay "see" these entities? I can buy that there's a moment or two when the transporter process first begins where it's possible to see the world around you swirling through all the phased matter. But it's ridiculous to think that you can reach out and grab something sharing the stream with you and simply bring it back with you. Reach out with what? You don't have arms (or eyes, or legs, or teeth, or hair). You exist as a pattern of energy.
  
  I'm usually willing to overlook questionalble science (except when it's REALLY bad, as in the upcoming "Rascals" episode) but this is pushing it a little for me. Although I believe this episode is well paced and interesting, this terrible science drops it down a bit.

  Barclay is such a terrible character. One of The worst episodes of the 90's.

  Any episode with Barclay is both boring and annoying to watch.

  Goddammit i hate the character Barclay, annoys the shit out of me in so many ways, what a twat, how the hell this supposed character ever got into Starfleet beggars belief, he gets even worse when they regurgitate him in Voyager.
  
  Dwight Schultz should have retired from acting after playing Murdoch in The A-Team as it was the only character his stupid face fits.
  
  Even Neelix is less annoying than Barclay

  Don't get why this episode is voted so low. Love Barclay, unlike the other commenters, and think he's a delightful addition on the show. Dwight Schulz nails this character, and honestly, this episode really addresses the elephant in the closet: transporters are scary, when you consider the implications of them.
