Ok I finished reading it and my first comment is half right :D
I still dislike a fair bit of the travel ones except that perhaps I just have the wrong ones in mind. Some of my favorite YT channels, if I watch it, are people like the Outdoor Boys which is not technically a travel channel per se but it's great how they come up with content all over the world that's related to fishing and things like that.
I despise the idiots who do a 15 second clip of their tits or ass on something like the great walk of China or something.
So in short yes I think I dislike the lame ones and appreciate the good ones. It's gotta be outdoor or survival related for me to enjoy it. I can't really watch someone who visits Rome for a video but that's me.
