Well, while Uncle G’s aerial video was quite spectacular (as aerial videos usually are) the venue was wrong (certainly not the canal we know & love) and overall I would join with Bodge in giving Kermit my vote.
It was quite an artistic effort from our sick little frog however I must agree with one comment (from one that shall remain nameless) that the shot of the sewer stormwater discharging did take away from the overall ambiance and would have better been left out. Same for the finishing shot of the rubbish treebranch stuck in the mud.
Other than that I thought the clips through the trees & grasses were a nice touch.
Hope you got written permission to include the kids in your video though, you know how much of a stickler for political correctness YouTube has become of late.
Just my thruppence worth!!
