This is a primer copycat, its very well executed and has the benefit of being amusing.
Acting is on point, especially the villainous Terry, but you have to wait the second half to understand what you thought were gaping plot holes. This is very different from other low fi sci-fi flicks pride themselves on following their own rules from the beginning end (primer, timeliness, triangle, etc).
The two lead characters are also fairly unlikeable at first, especially the female lead who seem to have even less self respect than the male one. This sort itself out mid flick, but don't expect the level of insane detail found in say, villeneuves' 'enemy'.
My biggest and only gripe are the inconsistencies in object purposes, as for example the rmemory Helmet becomes a time machine of sorts 10 minutes
I'm surprised this is not more popular.
