Ok, first off, I have to agree with you about Newcastle. Waaaaay too much flavor in that beer, it's sooo heavy, and if you're planning on drinking alot of it? Prepare for a tummy ache. With that said, on to the review!
Once again, there are a few angles to bring up about this video. I will say right off the bat, for what you are trying to accomplish, you succeed. You are obviously not trying to be a joker, you're not trying to be some outlandish internet personality, you are simply trying to give good reviews of a product you are passionate about, and in the context of your intentions, you pass. The ONLY criticism that would be a hindrance to those intentions is the edit you did in the middle where one scene bleeds into another, it was edited strangely and confusing to the viewer. Other than that, your goals have been met, you told me most everything I could need to know about this beer, mission accomplished.
The only thing to think about is that you have niched yourself with these kinds of videos. This is not a bad thing, it is a difficulty you have two ways to work around if you want to grow to having a very large sub base. The way I see it you have two options. Your first option is for you to leave the videos as is, and find your market. I don't know how to do this, but because there is very little entertainment quality to these videos, just like with Michael's video, the only people who will be interested are people who share your passion for beer and are "connosiuers (I have no idea how to spell that word)" of it. I know they are out there, you'd have an easier time finding them if you reviewed wine in my opinion. Wine is a beverage that more people who drink it are interested in the intricate details of it's make up and taste and quality. Many people who drink beer drink beer to feel good and kick back, and aren't worried about the suttleties, but people who are are out there, and if you can find them they will love your videos.
Your other option is to spice it up. There is a PBS quality to these videos, very informative, but not very eye catching or entertaining for the person who's just looking for something to kill time and make them feel good. Some ways you could do this is by making the short 2-3 min review, then if you have some buddies you have some fun banter with, film you all drinking the beer and cutting up. Maybe throw some of the most funny/entertaining parts at the beginning to get people to watch through the review. You could try adding some comedic elements of your own, but only you know if you have what it takes to do comedy, not everyone has that personality type. You could also do cutaways to other videos to help with the humorous side if you have a hard time thinking of things, but this of course will ruin your chances of monetization if you use copyrighted material, or will be a pain in the a** if you spend the time necessary to find material you can use. But the concept is you say "This beer didn't really float my boat" Then show a video of something choking on the cinnamon channel for a few seconds, then cut back to you, things of this nature.
So it's all how you want to look at it. You can try to add some comedy and pizazz to WIDEN your audience, or you can put your effort into FINDING your audience instead. These are the two best bets I see for growing a channel with videos like these.
I totally respect and value your opinion!! And, thank you for the kind compliments on the actual song its' self..I'm super happy that you like the song!! I'm glad that you got the message, and can't believe you called if flawless! Wow, thanks! Yes, you hit on some good points there, I will definetly maybe try and look more into the camera....lol I do tend to stare off into space in the some of the shots. I noticed I don't really smile in my videos..so I definetly need to try that more........one thing I realised I didn't do in this video was just STOP the camera on the scenery......so, in my next outdoor video, I will make sure there are more still shots. I found I was really rushed when doing this video though because I had the three kids in the van with me hahaha and they get anxious when sitting in the van too long! "we aren't film makers, we're musicians making videos'...yes, that's true.....you're very insightful! And you rock
