the writing:
nameless guy wanders off to take pictures for no reason, takes 2 pictures. slender comes and kills him in what amounts to 2 sloppy jumpscares. i dont have a problem with the nameless guy, or the use of slender, but to really expect it to be scary or even slightly startling is beyond me.
the presentation:
slightly flawed shading encompasses a decent forest that is unnaturally well lit. the introduction shot makes no sense though because the campfire in addittion to the people sitting around it didn't matter and werent the focus. it really didn't make much sense to reveal that, nor did it make sense to use slender as a title. that takes away any build or tension to what the danger actually is. the slender animation was above average, as is most of the frame by frame, but its fairly cliche in facial expression, the coughing of blood, the use of shadows to lead into a jump cut, etc. the entire thing feels like you just wanted to throw slender somewhere without actually building to it.
the sound design:
top notch. even though its jumpscare poop sounds, the static was ok, and the music was well implemented. too bad it was good to a detriment because ti was genuinely tense and creepy while the flash was kind of small and cliche.
the verdict:
cliche, boring, jump scares along with a character who is introduced in an environment that makes no sense runs away from a thing and dies while pretty good music plays, and visually executed ok. its middle of the road and lacks anything that i would call part of a great flash, but has its audience i'm sure.
