Calling this a "Poor man 's eternal sunshine of the spotless mind", is pretty silly and lazy, and just not true. Having similar themes, does not make you a copycat. This is not like the above mentioned film at all, save a few thematic similarities, the execution could not be more polar opposite. Saying too much would ruin this film as it does have a lot of twist and turns. I would recommend not watching this if you dislike slow-paced films or dislike low-budget films that rely mostly on storytelling.
This movie was interesting enough that I watched it over the course of 3 days because it made me interested in what happened to the character. This is really what set this film apart for me from so many other low-budget films, I truly did care about what happened to the main character, and by the end of the movie, I was deeply saddened There was a good enough mystery here that the film holds together until the very end. The acting is decent all around, especially the lead, he carries the entire film and he does fantastic. The cinematography is good(though the shaky camera work may bother some people}, the script is not bad, it is quite decent and cleverly constructed(I was reminded a little bit of "Momento" as I was watching it). While it can be confusing at times, verything gels together by the end, but you really have to be patient.
The exploration into memory, trauma, and how we deal with it is interesting, and I felt it's take on it was refreshing. The later "Reveversion" has similar themes. By the end of it, all the character has gone through, and will go through, is a bit heartbreaking. This is a very sad film, it is bleak, and to be honest, without hope by the time you realize what is actually going on.
This is a well-made film that deserves a bigger viewership.
