If you're going to resurrect a (then) 20 year old movie franchise, you have to expect that the now grown original fans might be interested. The excuse that "it's just a children's movie" falls flat. Like it or not, adults were going to see it, and they expect to be entertained too.
This comment makes no sense to me. Lucas has always included characters for children in his Star Wars movie - R2 and 3PO, the Ewoks, and Jar Jar. Disney continued this tradition with BB8 and the Porgs. And not everyone loved them. I wasn't a fan of the droids and the Ewoks when I was a teenager and I'm not a fan of the Porgs. But I've never developed this deep-seated hatred for any of these characters the way many have toward Jar Jar.
This deep-seated hatred toward Jar Jar Binks, who is nothing more than a clumsy and naive character makes no sense to me. Ahmed Best was nearly driven to suicide? I think the Star Wars fandom had sunk into a level of insanity over their reaction to Jar Jar. I find it ludicrous and extremely irrational. And whenever someone explains why they hate Jar Jar, his or her explanation comes off as irrational or lacking in any logic to me.
