Lines and theme are two different things. Lines = ridiculous, yes. Theme = ridiculous, no.
As a whole the JC is not meant to be ridiculous, but is there a little fun to it? Yes. Take the lines away, the ride itself (for the most part) is relatively realistic, or at least trying to appear to be. That is the point I am trying to make. When you're trying to make the queue, boats, animals, and sets appear rustic, antique, set up a theme as if you're in a jungle, and adding a little bit of mystic with the cave, as well as other enhancements over the years you're obviously trying to take it a little seriously.
So, yeah, it kind of defeats the purpose if you make it look like Christmas exploded all over the place. So, yes, it looks a little ridiculous to me and doesn't go with the theme in my personal opinion. Sorry.
