I like the Ewoks, too. Accept it or not, Star Wars will always need a couple spoonfuls of 'cute' to be Star Wars. There are lots of quality movies out there that are just for grown-ups. Star Wars shouldn't be among them.
I feel the same about Jar Jar; sure, some of his gags tanked, but without him, The Phantom Menace would have fallen extremely flat for the little ones. My son was born in '99 and he always liked Jar Jar (I said nothing about the character's general reception, because I wanted him to be able to enjoy or not enjoy the character on its own merits). And enjoy him, he did. I confess it kind of bummed me out, years later, when he 'learned' that 'everyone hates Jar Jar', and 'Jar Jar is for babies'.
I guess I'm at least thankful that the adults around me, back in '77, didn't feel the need to tell me that R2-D2, the Jawas, and mouse droids were 'for babies'...
