British Reviewer 4.4/10

The actors tried really hard to make something of a very thin screenplay. The plot was fine, the visuals actually great for what was clearly a tiny budget and the editing good.

Harvey Keitel was chronically underused but maybe that was a contractual thing and Kurylenko was quite decent although not believable as an ex-addict; too beautiful!

The main problem for me was the poor screenplay, script and pacing. The plot crawled along at an agonisingly slow pace at it's worst and the twist incredibly improbable.

Still, it's better than Twisters and A Quiet Place: Day One on a fraction of their budgets.

Ok, I didn't fall asleep, but this was painful to watch. Another reviewer said it felt long despite being 88 minutes and I have to say, I was convinced this was 2 hours or more.

I'm American and tend to only like American films, but I saw The Courier a year or two ago and Olga was great and the film was far better than it should have been. Gary Oldman brought his game and I thought Harvey would do the same here.

The plot was weak and I found it hard to care about any of it or the people involved and of course, everybody was stupid and made the wrong choice leading to the overall mess that this movie was.

No idea what the budget was, but this movie was so bad, Matt Damon couldn't have saved it.

Paradox Effect was a pleasant surprise. I didn't have a movie to watch and after scrolling through a number of films that I didn't want to watch, I thought I'd give it a go. I didn't know what to expect. The story kept me going and twist locked me in. I really like this film and wanted it to be longer.

There is never enough Harvey Keitel in any movie but loved to see him every time. The action was exciting and Olga Kurylenko is so underrated, she is beautiful and a fantastic actress.

The director made some stylish choices and the movie looked great. Im pleased I made the choice and watched the movie.
