Don't apologise. You're just attempting to trivialise or simplify something you don't much like in order to make those who enjoy it look foolish, you can be honest about that. Everything is subjective and the whole Avatar thing does nothing for you, fair enough and I wouldn't try to change your opinion on it because ................................. well there's no reason to.
But the reality is that everything you love can be trivialised also, but why would anyone feel the need to do that? Ultimately a plant that lights up is a plant that lights up but what were you actually expecting, naked ladies cavorting provocatively whilst juggling chainsaws singing opera? To some it's the way the lit plant makes them feel that they enjoy, not what is physically creating it. Some see beauty in the colours and tones, the fact the image makes them feel happy and takes them to another place rather than just thinking "oh plants that light up".
Yes that's what they are but then again Michelangelo's 'The Crucifixion of St Peter' is basically 'a doodle of some guy being mugged, wow amazing' by your logic. In fact you could save a ton of money and instead of paying to see fireworks (some bits of fire in the sky, wow amazing) you could just light some matches and flick them in the air "Hey look kids, who needs Disney and their Wishes firework show this is just the same thing'.
