Great concept, poor execution

Rating: 6/10 (24 March 2018)

I have to admit that the trailer really piqued my interest for this movie, especially after seeing all these scifi-ish scenes combined with some partially terrifying and strange shots. I won't lie, I extremely enjoyed most of this movie, however there were too many plot holes, and after a certain point I even stopped caring.
So, we've got the beginning of this movie, where the protagonist reunites with her mysteriously disappeared husband, but a few moments later his situation is critical, and while being transported to the local hospital, they're surrounded by a tactical unit who extracts them both and moves 'em to a secure location. It was going smoothly but from this point onwards, logic jumped out of the window:
-The protagonist is being "greeted" by a depressed psychologist, who -even though she technically stated that our dear protagonist knows too much to be let free by refusing to comply to her request to talk to a laywer- she proceeds to give a full briefing about the so called "Area X" and technically offer her a job.
-So far, we've got a medium sized research facility with scientists in hazmat suits and random volunteers who monitor this site, where's the military? Seems like there were some extended budget cuts for the army, assuming this anomalous event must have been the biggest humanity threat they've ever encountered but they're treating it like a rat pandemic.
-Plan is simple: No plan, we just need to get to the lighthouse. As mentioned earlier, they've been sending teams of military personnel in the zone for the past 3 years and the only person who returned is spitting blood and having a massive internal bleeding. Sounds cool, let's gather a team of 4 female researchers (and a paramedic), give them some M4's and send 'em in! That's what happened. Who cares about additional protection, masks, helmets, night vision googles since you know.. it's a damn tropical rainforest in there. I actually wondered if this was a Hunger Games sequel, sending 'em there to kill each other with minimal equipment and having to survive on their own.
-At some point, a member of the group is being grabbed by a mutated crocodile, and rest of the team literally stands and watches them. Guess what's their next move, use tiny boats to cross the river, hey, there really mustn't be any similar creatures lurking in the waters of this god damn swamp.
Worthy of mention is when they firstly entered, and they stated how communications weren't working. Oh, oh! You've been sending people in there for a while but you just noticed it. Also, by their reaction when they firstly encountered the mutated plants, I've concluded that all the other missions in "Area X" had the sole purpose of getting to the lighthouse by any means necessary, and that nobody conducted a reconnaissance in the primary part without immersing further in.
Finally, there were a few minor details that also got my attention like, if this place was so classified and well protected, how did the sergeant manage to get out and breach the "24/7 surveillanced" perimeter? Plus, when the researchers watched the video of the army dudes cutting off a part of the mutating mans body, the reaction of the paramedic felt pretty unreasonable and weird, judging from her damn profession.
I still really enjoyed it and loved the atmosphere , sort of reminded me of Stalker. I'd say Concept gets a 8/10 while Execution is like a 4/10.
