  • This was a great pilot episode.

    I really liked the pilot episode to Threshold. This episode showed how good the show can be, its just a shame they don't have more episodes as good as this. We are introduced to a woman named Mollie and her team. They have to search a boat to see if aliens really have landed. So they start Threshold which is desigmed for alien incounters. But when they team get to the boat they find a whole lot of weird stuff, and they never get to watch a video of the alien. Most of this episode was very good. I really liked it and i know this show should have gone on for longer.moreless
  • A great series premiere.

    Nothing makes a sci fi show better than starting it with a mystery. After an alien craft attacks a naval vessel, the US government dispatches a scientific team to investigate the incident. It's a very exciting start to a show. The guy from Lost plays another creepy character on this one. The plot makes use of an alien spacecraft that attacks a navy ship. A government team goes into the ship to figure out what happened. Things go bad when they find a survivor who changed into something that they can't explain. The team scuttles the ship and they dust off to safety. This is a great show.moreless

    Why do all the good shows get pulled to make way for more ignorant "reality" shows or disgusting filth like book of daniel.

    This series had an interesting twist and I hate that some exec made the decision to cancel this show when so many really enjoyed it.

    Apparently the only things on tv anymore are so-called "reality" crap that truly are not real people or sports or there has to be homosexuals romping all over the screen.

    I'm sick of the junk flooding the airwaves. How about some quality Tru Calling, Judging Amy, Joan of Aracia to name but a few others that were cancelled before their time...not disgusting enough for the losers of the world apparently.moreless
  • Two Guys, a Girl and a Dwarf

    An atmospheric and promising start to the series, I was initially hesitant of tuning in to Threshold, as I usually find straight-forward sci-fi shows send me to sleep and I wasn't excited about the wave of mystery series flooding the networks after the success of Lost. Thankfully, the first part of the Threshold pilot is an enjoyable hour which skilfully introduces us to the regulars and the main mystery of the series.

    Trees Made of Glass Part One sees members on a Naval ship succumbing to the terrifying after effects of seeing a strange light in the sky. They turn insane and kill each other. Dr Molly Caffery is sent in to investigate the possible extra terrestrial entities behind the attack and with the help of a team of scientists, she manages to get video evidence of the light in the sky and meets the soul survivor of the ship, who seems invincible.

    Carla Gugino is, unsurprisingly, excellent throughout. She's a seriously underrated actress and after her last series, the criminally cancelled Karen Sisco, went to the big TV set in the sky, I was happy to see her return to the small screen. She makes an immediate impression as Dr Caffery and her co-stars are also good. Brent Spiner and Peter Dinklage also being notable.

    The one bad point about the episode is the slightly annoying overuse of revelations. There's a lot of details to stuff into the first part of the pilot and it's difficult to remember everything which has just happened. Hopefully this will be changed as the season goes on.

    Despite some, hardly terrible, problems, this is an effective pilot which manages to walk a fine line between sci-fi, mystery and horror.moreless
  • An alien signal transmitted alongside a naval vessel and the subsequent disappearance of the vessel's crew leads to the activation of a secret government program to contain and investigate various pandemic outbreaks.moreless

    I was casually browsing the channels, when this episode caught my attention. I quickly decided that Threshold would be the one series that was worth watching on Friday nights, and I was eager to see if next week's episode would be as good. The show's writing was plausible and exciting; it had quirky, but likeable characters; and the acting was well done. Finally, I had found a science fiction series that was interesting without being too outlandish. I realized though that, because the series had been relegated to the dreaded Friday night time slot, this series was probably going to be short lived.moreless

Trivia, Notes, Quotes and Allusions


  • TRIVIA (5)

    • Goof: The reason they blow up the ship is because the North Koreans also detected the probe and are on the way to the ship. Then later in Tree's of glass part 2, they say "what did Gunneson swim the 80 miles to shore" saying that the ship was only 80 miles off the coast of the USA. How could any Sub from a hostile country get that close to the USA at all? International waters don't start for 200 miles from the coast. or even that fast? Why could they not just tow the ship away.

    • Goof: The blood packs used when Gunneson is shot by Caffrey are visible underneath his shirt.

    • In the bathroom, Ramsey's jacket changes position several times. Sometimes it's over his shoulder and sometimes it's pulled back.

    • Our heroes find the camcorder in the rec room and watch it. Scenes are filmed in the rec room. Then the operator goes up on deck.
