Okay after looking at a couple of your videos I would say there is one big thing you to work on which is your Audio. Your coming in very soft at times even wearing headphones like I do and having youtube cranked to max your soft. I would say you should invest in a Mic that may help, Also I would say avoid filming in your car unless you got a really nice camera that can pick up everything your saying cause that was when you were the softest.
As someone who does review of video games I think the biggest thing is you need to show a little more energy when doing the reviews on camera. It seems like your just reading from a script and nothing else. You want to give out your reasons why you loved this movie or why you think this movie was crap on a stick. If you get excited about something than your subs will do the same. I think right now what is holding you back right now is your audio issues, I think if you get that corrected it will help get people to watch more. And also promote the crap out of your videos when they come out. On here, Google+ Places like you want everyone to see what your doing and people will check it out. Especially if it is a new movie that they are curious about cause people like hearing from different sources before they want to go and waste the money on a movie.
Intro is good nice a bright, little loud, but very nice work and I would say you should call yourself you channel name instead of you regular name. It makes people associate your channel to that name the more you use it. Its why guys like Markiplier always use his when he does his intros, its your brand and you want to promote it.
Beyond that good luck in your future endeavors.
