Dermot plays his usual average bad guy role, and I just checked and there are 142 films with him in it, all mostly playing the same sleaze villain. Not much range, but it's expected.
The other two actors have loads of experience as well, but as of yet have not have much of a break out role. Add to this a new director/writer and you basically signing up to watch an average film at best.
The problem is that it is so straightforward and predictable that it gets boring rather quickly. Throw in a few "of course" moments to create plot points and move the film along it's path along the railroad track.
The ending isn't much, but again, as expected and wrapped up quickly.
1/10, as this movie doesn't bring anything to the table, no action, no tense moments and therefore no reason to watch it as there is absolutely nothing new here.
It wouldn't surprise me if this was a AI generated script based on previous movies of the same genre. Might as well start replacing Dermot with and AI clone as well as he's never going to change either.
