I made a point of watching at least a tiny bit of every single paralympic sport at London 2012 (I was having a very similar conversation to now with a friend then) and genuinely didn't really enjoy any of them.
Like I say, if others like watching the different events (and they clearly do)...
Not doubting the endeavor that they put in, but IMHO it doesn't make for a great sporting spectacle. But, as you say, each to their own. I won't be tuning in to any of it, but I'm sure others will enjoy it.
