The idea behind this film is decent but the complete lack of budget and poor execution makes Repeat barely watchable. Watch it for the story and try not to let the laughable science turn you off.

Joshua Ford and Tom England were so good in the 2019 film Cosmos that I found and watched their 2021 film Repeat as well. The acting is very good but the plot details are absolutely implausible and I'm not referring to the idea of communicating with the departed; quite the converse, I'm referring to the premise in the movie that the protagonist's work finding a reliable scientific way to communicate with the dead is hardly noticed at all by the public or fellow scientists. In actuality, such efforts and research would make worldwide headlines (even if it was quackery), so that aspect of the film, that his work was only know to a handful of visitors to his public demonstrations, was not credible. Also that the low-budget "equipment" he was using was clearly car boot sale junk was somewhat detracting from the film, although that in itself was overcome by the excellent acting and was mostly overlooked at least by this reviewer. Additionally his use of radioactive materials for his machine pilfered from a storeroom while not in and of itself unbelievable, becomes unbelievable due to again small but important details, such as storage and transport in an unmarked petrol jerrycan, and "holding a mask on his face", rather than actually wearing it properly, and mild radiation symptoms where actually he would be seriously ill in hours or days, was also very thin on attention to believeability. So this movie was not the best vehicle for the excellent talents of the actors and actresses who all turned in very good performances. Watchable but not believable.

I found this movie had a really interesting take on the theme of alternate realities and is one of the few movies in this genre where I was left saying "Wow, I didn't see that coming" which was a pleasant surprise. The story also did a good job of keeping the alternate timelines together and cohesive. I really enjoyed it. One note: This is the type of movie you can't leave to go get a snack, etc otherwise you will be lost. Get everything you need ahead of time and pay attention to the details.
