Did they purchase votes?
I've heard that you can buy Twitter followers. I've even seen a web site that lists how many followers you'll get and for what price. Is this possible on the IMDB too? Reminiscence: The Beginning has a 7.9 rating with 1,175 votes. Yet it has only three topics on the message board (now four) and only seven written reviews. Six of those seven were written within a three day period back in 2014. Pretty strange.
Anyway I found this film to be really boring and I couldn't make any sense of the plot. Really bad. A lot of it looks like it was shot on a handheld digital camera, something I can't stand in cinema.
