It's actually kinda so-so without the whole thrill ride aspect of the theatrical experience. In retrospect, the film wasn't that much of a "realistic" take on a giant monster attack like the producers wanted. Instead of merely being about people attempting to make it out alive, we have some guy trying to be a Hollywood hero and moving towards the danger zone to save his ex, dragging his innocent friends along for the epic (ally idiotic) trek. All of the drama in the movie resulted from a relationship we don't really know or care that much about, and their whole journey to save this woman is rendered pointless because everyone dies at the end anyway.
Although, one could interpret it as an epic tragedy within a monster attack scenario. We have the hero who has a single major flaw that leads everyone to an inevitable demise: the incessant need to think with his dick. The moral of the whole story could simply be "bros (and sistas) before hoes." Hell, before the main guy leads them all to their end, his literal brother is the first one to get axed. While he didn't exactly die due to the main guy's tragic flaw, it does foretell what will happen to everyone if they all decide to ride their faith on his penis. On their journey, they encounter a gargantuan creature with a mouth shaped like a toothy vagina, and they also have to face its crabs. More signs telling them to just run back. The movie tries to push things further by having an anti-unprotected sex message in there. One woman gets assaulted and infected by one of the smaller creatures, then balloons up and explodes moments later. Right after we wasted spent a fair bit of screen time witnessing the courtship between her and the guy filming everything, no less.
This movie may be more complex than I originally thought. It still isn't the most realistic portrayal of a group of people trying to survive a monster attack, but I think there's something deeper to the whole experience.
