First of all, it's not for everyone. It might seem repetitive, too long or stupid at times. However, it's worth a shot merely because of it's visuals and the constant intrigue whether the protagonist is to believed or not. The so-called 'plot holes' in the movie are open to interpretation and thought and never bothered me. The ending could have been cut short, but it's a reminder that perhaps there are no good guys here. Seems to be a product of another era, perhaps too ambitious for its own good.
