Cath Clarke Guardian Jun 9
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
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

Captain C @RT29629362 18h I think this movie was trying to be too cerebral without having anything profound to say. It was kind of like Contact but without ANY human element. Imagine you had an idea for a neat alien concept - but then forgot that you need to tell a story and just stretched your idea into ‘how would they figure out what this neat alien thing is?’ And wrote a script that is pretty much that - and only that. Felt like this could have been an interesting episode of X files. Or a vignette on some anthology - so like, 30 minutes max. I wonder if people pitch an idea and then expect a $100M budget and are given $1500 instead and told to make the best of it. That’s this movie. I watched it because I like Josh H and Dennis Q. But even they couldn’t make this interesting. Best part? David Thewlis - great misanthropic, British genius. Put this performance in a Bond movie or something and it’s brilliant. See more Joe B @RT45187721 1d "they're not ready" - Yes none of these people were ready to make a sci-fi movie. Terrible sci fi writers will often use a voiceover / narration explaining everything for exposition. (at the beginning) This genius takes it one step further by also adding a voiceover AT THE END TO EXPLAIN EVERYTHING. Because no, we didn't get the premise so simple a toddler could understand, please just lay the whole plot of the movie out for us with a narration at the end. Thanks so much. Please, Jonathon Sobel or any other director who reads this...if you don't like sci-fi, or are not or never were a fan of sci-fi. DO NOT MAKE SCI FI!!!! If you've never read a full sci-fi novel just for fun, DO NOT MAKE SCI FI!! Or if you you ever find yourself saying 'hmm sci fi sounds fun, I could use my hollywood clout to try it out" .... DO NOT MAKE SCI FI!! There are so many other genre's you can go mess up for profit, just stop. See more Ashlynn H @RT73457234 1d It’s like watching the corniest young adult fanfic on the screen. I have no clue how anyone liked this, it’s cliche after cliche after cliche. And the characters have no depth, just cut and paste like an AI amalgamation of the most stereotypical sci fi alien movie ever. Of course they all solve each problem that comes up on the first try - how to speak to aliens, how to read the aliens response, etc etc etc. and their old childhood memories give them the magic solution that leaves them rushing out of a room while the other characters yell "where are you going" after you as you visualize and solve the mystery! Complete with a military ambush to try and stop the science nerds from talking to the aliens! See more Peter K @Vacadoug Jul 31 This production makes one realize Earth's position in the grander scale of the universe -- well done -- forces one to ponder and think! See more Jason M @Nautius Jul 12 Very good, cerebral movie! It is the classic "could we" versus "should we". It intelligently challenges our concept of what we think think is alien and completely dismantles it. See more Ayatollah of D @RT42595533 Jul 7 Awesome movie. Cerebral. See more Read all reviews
