Oh look, I am writing an actual review!!!11eleven
Well first of all, the animation seems abit...lazy? When I look at the characters I am kinda under the impression that the animator is one lazy bastard (no offense :D). It was good, considering the flow and it created a well received cartoony atmosphere, easy on the eyes and all in all enjoyable to watch.
I do have a more serious issue with the voice acting part, the voices were relatively good, but the actors should get better mics. This is more important than you think, a good example of well sounding voice acting was Robert.
Writing. The plot itself seemed cliche...the whole love square thing, though a German exchange student was a nice touch (the more popular are Russian and Swedish, but I think you can go even more original than German...something like Jordanian maybe? or Latvian). Humor was good, though sometimes supressed by awkward and seemingly unneeded moments. You automatically get a 5/5 for the Yogi Bear refferance, but in a detailed review, this was more of a 7...barely.
Overall: Pretty darn good, enjoyable and I wouldn't mind watching other cartoons from this series. I'm guessing the voice actors are your friends, so tell them to save a few dollars for decent microphones...but if they aren't your friends and can't get new mics, then I suggest getting new voice actors. You'd be surprised how much talented actors (with decent mics) are waiting for a chance like this (inclueding myself).
Take care, pick up on your skills and good luck.
(Holy crap, I think I just wrote a real review)
