As headline says, "Confession" film indeed has some potential. The story line is not that bad. What destroyed this film is that they made it real short and left a lot of details. My opinion is thay this kind of story line really needs to go deeper and should have presented in details, so that it would be more interesting. Now, maybe because of low budget, so, they made it really, really short and hence, it couldn't make it interesting as it should have. While I was watching, I even felt that it was kind of boring because the presentation style is kind of dull and cold. I only kept watching because I wanted to know whether Victor Strong is a bad guy or not and what he called as the truth. Otherwise, I would stop watching even though runtime is just 1 hour and 20 minutes long.
Anyway, they had a chance to make this film a bit more interesting. Too bad that they couldn't make it and it turned out to be low budget, a bit dull and boring film. If they could make it interesting, I might give more stars.
BTW, I forgot to mention one little thing. Thriller? It's what the plot says. But I didn't find anything that made me thrilled. I watched the whole thing with normal mood.
