Frankly, I think the entire concept of a video review of a model kit is silly... Moreover, the few I've viewed are just too hard to watch... No or poor scripting, dialogue rife with "Ahh's" & "Umms", Bad to no lighting, poor contrast, akward camera angles, lousy back-drops, bad sound, sloppy, jump-cut editing, off-camera noise, etc., etc., etc....
I can safely say that I've NEVER purchased a kit based on a video, written, or any other kind of review... What influences me is, in order:
1. Subject
2. Scale
3. Price
If the subject doesn't interest me, it stops there. If the subject is one I want to build, but not in a scale that I like, then it's a pass also. Then, if the subject and scale are enough to hold me, then the price of the kit is the deciding factor.
For instance, if I just HAVE to have a 1/48 scale P-51D, and there's two kits in the shop, one being the latest release from Tamigawa or Trumpedupeter, which received glowing reviews and the other is the old Monogram P-51D, the Monogram kit is gonna win. Why? Simple... $12.00 vs $39.99...
I don't even look for reviews before buying a kit, I kinda like the surprise when I open the box for the first time. And part of the fun is hitting a problem area and figuring out your own way around it.
Double-ditto...
