3/5
The film has a clever dodge for avoiding the inevitable silly moment when the aliens are revealed but, in a few too many scenes, this is a bit more snore than awe. Go to Full Review

3/4
It is a fantasy, but it’s more confrontational than escapist. It doesn’t want us to turn our brains off. It wants us to think. Go to Full Review

3/5
Other cerebral sci-fi films such as Contact or Arrival may have already answered some of the questions posed here - and with a much higher budget - but this is still an intriguing contemplation. Go to Full Review

3.5/5
Consisting mostly of rocket scientist conversations about astrophysics, 'Signal One' is nevertheless far more intriguing than anything in 'Disclosure Day.' Go to Full Review

6/10
It’s fascinating to see how low-budget science fiction explores more obscure and interesting stories than blockbusters like the recently released Disclosure Day. Go to Full Review
Charles Johnston Spectrum Culture Jun 8, 2026
A trippy, eccentric sci-fi film, more thought-provoking than entertaining, that eschews easy tropes to deliver upon its urgent message as clearly as possible. Go to Full Review

TheMovieSearch R @TheMovieSearch 1 day ago Signal One explores the search for the unknown, bringing skeptical scientists in to investigate an alien anomaly. As they uncover new information, they figure out how to communicate with it. The premise has potential, and the cast holds its own, but the performances never become powerful enough to make me want more. The screenplay is where the film struggles. It is missing important details and the credibility needed to make the situation convincing. There is back-and-forth without enough explanation to connect everything. I also was not a fan of the twists involving the alien dying and coming back. The story becomes a jumble that is more confusing than entertaining. Ultimately, Signal One never delivers on its premise. I wanted a stronger story, clearer explanations, and more suspense around communicating with the unknown. Instead, the film feels disconnected and difficult to follow. It is fine as a streaming movie, but it is one of those films you will finish and quickly forget. See more Jason W @RT12053935 3 days ago No budget, extremely wordy without much actual thought or emotions in the script and plot. I decided to watch it on a whim and oh my God I want my 2 hours back. So much could have been done unfortunately, so little was done. See more James L @Jag87Up Oct 10, 2026 Trust the people who have watched it NOT the professional reviews. This is fluff disguised as something deeper. SLOW, inane writing/conversations. It is super boring of the four of us I was the only one who did not fall asleep. Outstanding actors/actresses horrible script. Love all the people in it and they are not to blame, they did fantastic but could not save this train wreck. Art-house nonsense. The talk of quantum mechanics was not well grounded in actual science. See more Moody C @MoodyC Oct 5, 2026 Really low budget sci fi. Not much happens & CG is so bad, you prolly seen better on YouTube. It's about communicating with aliens but there are obviously better ones like Close Encounters & Arrival. Waste of time, total skip. See more Noah H @Noah85 Oct 1, 2026 Well, this was a waste of time. It felt like a complete Contact knock off. The characters were so lame, and they swore way too much for a PG 13 movie. I’m sorry, but I just didn’t enjoy this. Watch Contact instead. It’s a whole lot better than this pile of garbage. The only reason I’m giving this 3/10 is because the morph cloaking effect at the end was actually pretty cool. See more Donny W @DonnyBlanco Sep 19, 2026 If you enjoy sci fi, this is a must watch. Lesser than Contact or Arrival, but a good moral dilemma. See more Read all reviews
