Woah... o.0
Well, the idea is totally cliche and the mechanics are... Wait a minute... This is a PRO-Tails movie!! Honestly, for something that original I'd love to give you a perfect 10 (especially considering the common cliche here is to treat the poor guy like Kenny), however I cannot rate movies based on personal opinon, and therefore, shall give you a short rundown of the movie.
First of all, the drawings were rather cute and definetly similar to that of the old Sonic-style. Really reminded me of the old days of the Genesis/MegaDrive Sonic games (which are still among the best in my opinon). The Death Egg looked cool, Tails looked adorable, Knuckles, the monkey robot, and Metal(?) Sonic looked rather fitting to the theme of the soon-to-occur fight. Song was great and REALLY fit the theme of not only Tails on his way to the battle scene, but also of the hilarious review comments as well! The comment jokes were pretty funny and not bad for someone without too much real experience (and I'd know, as I've really been around!).
As for the actual series... Mind if I suggest having Super Tails make a cameo? You may or may not know it, but it's been WAY too long since anyone's ever seen any of him! ^-^ But hey, this is YOUR series, so do whatever you want!
Long story short, this REALLY has some great potential in it, and even though I've said it to many other movies, I really mean it. This is one series I'll DEFINETLY be following! Good luck with it!
