This film is decent, and I love "time travel" concept films in general, but there are few scenes that made no sense in the "no person would do that" kind of way, or contained too many "coincidences", which heavily impacted my ability to suspend disbelief for the remainder of it (the scenes in question happening about 1/2 way thru the film). I haven't seen anyone else complain about this yet, so I'll rant about it here: WHY did the lead protagonist use his DOG to test if he could bring back living things? No one would do that. No one. Not if they loved their pet. He would have gone to a pet store and bought a mouse, or a snake, or anything. He wouldn't use his dog! Also, why does this drug that seemingly randomly places people in the past (depending on where you are standing...okay?), always place them within moments of mortal danger? No one is ever just dropped in a random field, no, they are placed inches from death. A frozen Ice Age tundra with nothing for miles...but a caveman is nearby, or a 16th century swamp...with a conquistador feet away, etc., etc. This film would have you believe in the far past everyone was constantly within 7 minutes of being killed. It was all just a little "too much" for me and took me out of it. And no one would take their darn dog!!

The whole synthetic DMT aspect was something new and besides time travel i thought they were going to go even more weird with it.. But they didn't. And that's kind of a shame considering one of the many report people have from just normal DMT is talking to inter-dimensional beings or aliens. I thought the scene where Mackie goes to the voodoo serimony would have been a good jumping off point for adding some more out there science fiction concepts related to DMT. The ending was very lackluster to me... a hero saves blah blah blah... I've seen that ending in 100x different ways.. fading into history to riding into the sunset..,. The first half I was much more into it, would've been a 8/10 if i stopped there.. the end took two off for me. But thats because i found it bland and uninspired. Would i recommend it... Not sure

If you are a fan of Benson and Moorhead's previous work, you will most likely enjoy this feature too as they maintain their same storytelling style that smoothly combines fantasy, horror and comedy. And with a larger budget this time, they're able express their mind-bending stories to a greater level. Specifically, the score and cinematography are great throughout the film and exceptional at some points. Also, both Anthony Mackie and Jamie Dornan deliver fantastic performances of two best friends who are struggling with their own personal obstacles. The story itself is unique in a general sense. But within the realms of the sub-genre that it plays into, it can seem somewhat typical if you follow those types of films. However, the approach taken to portray this story is unique. For me, this separated it from other films of similar narratives and it kept me engaged with the story and the characters.
