Hi
I checked out 2 videos:
1)InYourFaceHorror : Episode 17 : You're Next
2)InYourFaceHorror : Episode 16 : Mirrors
I think the actual content (the movie reviews with the comedy aspect) was pretty good
A few comments about the marketing side:
1)Your intro is pretty long on the 2 videos - about 30 seconds - That's a long long time in YT terms and if someone just lands on one of those videos, I'm not convinced they're going to wait it out. I was getting pretty impatient! How long is your viewer retention in analytics?
2)The video titles are not at all optimized for YT search. No-one will be searching for your channel name and if they did, you do not need it in your titles for your videos to appear. Search for my channel name and you'll see what I mean

If you want to get your name out there, then say it in your intro and outro and in your description, but remove from titles. Likewise for episode numbers. They are taking up valuable space that can be used for keywords. No-one is searching for episode numbers. Put your videos in a playlist if necessary and put the episode number in a custom thumbnail. So basically your videos are optimized for "you're next" and "mirrors". That is is pretty vague and could be anything (car mirrors, makeup mirrors...) - not just the movie. Do a search for it and you'll see "you're next" returns 23 million results!! You need to have titles like:
You're next movie review | Horror movie review
and then in the description, lace it with a brief summary of what your vid is about without spoilers obv but seeded with those same keywords that are in the title, but make it sound natural and don't go overboard.
Basically do some research on SEO (search engine optimization) for YT and follow the advice you find.
3)Custom thumbnails - Learn how to do custom thumbs that jump out of the page. The goal is to get yours noticed before the one above you in the search results. Big bright text that contains the vid title and more importantly makes it clear what the vid is about and . That way viewer retention will be longer.
4) I wasn't too keen on your trailer

Sorry, because I can see a lot of work and editing went into it, but it doesn't seem to go with the theme of horror movies. You seem to be in a well-lit office ?! Maybe something spooky with spooky music, costumes etc would be better?
