A fun, creepy "found-footage" web-series based on the infamous Slenderman mythos, "Marble Hornets" is good eerie entertainment! (Though not perfect by any means)
23 August 2014 | by (United States) – See all my reviews

A long-running web-series, "Marble Hornets" is something of an odd beast. On one hand, it's concept is great, and it's generally a well-executed example of the "found footage" sub-genre of horror.

On the other hand, I do find there to be many problems with the execution, holding it back from reaching the perfection it is capable of reaching.

But still, for fans of horror, this is definitely a must-see.

The series seems to predominately follow Jay, as he tries to solve the mystery of what happened to his friend Alex that caused him to seemingly lose his mind and withdraw from society. Told from a "found footage" perspective, the early episodes alternate between footage shot by Alex some time earlier that Jay is reviewing (during production of a student-film he was working on) and newer footage shot by Jay as he investigates the matter. Little does Jay know that the mystery of what happened may be linked to a twisted, possibly-supernatural figure known as "The Operator." (Based heavily on the "Slender Man" mythos from the internet.)

I'm quite torn by what to give the series for a score. As I said above, it's a series of strengths and weaknesses. And I fear that my decided on score of 7 may be misleadingly low, despite being a decent score. Because I do genuinely love the series. (Well, at least what I've seen so far.) And in terms of entertainment value, it's great for a free series.

I think the biggest strength of the series is atmosphere, and wonderful use of the "found footage" style. If you're in the correct mindset, this series will definitely creep you to the bone. While the quality might not be great, it comes across as generally "true to life", and there's a wonderful sense of pacing, build-up and payoff as the episodes continue. Technical aspects like composition are also well-handled. And I find the storyline incredibly intriguing, and definitely one that makes me want to continue watching.

That being said, I have some big issues. First, (and I hate to say this), the acting can be pretty bad at times. At least early on. It does rob some of the suspension-of-disbelief that is required for a "found footage" series. I also find the episodes to meander a bit too much. I feel like there is a lot of room and time that could be condensed and make for a more compelling experience. It can almost get boring here and there. Which makes it harder to want to sit through the episodes.

Thankfully, despite those weaknesses, I feel that the strengths make the series one that fans of horror (and especially "Slender Man" fans) certainly must at least try out. I think it's great fun. It has a good story. And it has some absolutely, positively spine-tingling scares.

I give it a pretty-good 7 out of 10. Frightening and fun, but not without its flaws.
