Well, it's the groom's first wedding. And Kim eloped the first time around, so it's not like she's soaking her guests for presents a second time. So I don't really find them having a BWW tacky in and of itself. There are tacky elements to this wedding for sure, but I don't mind that they had a big wedding.
The family wedding vs. TV performance question is interesting. I have no idea what her contracts with E are like, but I doubt cutting down on cameras/crews was an option. Also, I'm wondering how accurate the reports are that she had to actually uninvite people. I've heard a few reports of people receiving last minute invitations. (Which is its own thread, I know.) So I don't know what's true. It'll be interesting to see the Kardashians address these things in the coming weeks.
