I really like the style you've chosen for your reviews, and you've got a really great voice/character, but I think you'd gain a lot with just a handful of more edits. There are some really great moments that the unfortunate, eventual, and completely excusable stumbles detract from. Monologues aren't easy, but you should be able to cut around those moments, and keep the image of the otherwise unflappable Count clear in the viewers' eyes.
I'm assuming that you set up the camera and just sorta do a once through discussion, riffing along with a general outline in your head. What I'd suggest is to run through a segment once (and by segment, I mean single series of complaints or commentaries not the entire review), watch it to reinforce those points in your head, and then run through it and record it a second time. THEN, when it's all said and done, watch the entire thing, and find specific points that you want to underline and emphasize, zoom the camera in and run through those spots a third time. That (and the occasional cutaway) should give you a nice solid chunk of material to cut between.
Editing can be a pain, and doing this would make the amount of time you're spending on these grow by a good bit, but I think that in the end it would be worth it.
