I'm glad those who went did have a nice time. It's not something I, like many I feel, felt they could support given everything happening at the club at the moment. But that doesn't mean others can't go there for a nice day out.
I agree it's a shame about the overall attendance, but it was abundantly obvious that would happen. There is little to no hope around the club or in the fan base at the moment after the last two years, so I think a lot of people (myself included) are relieved we're not playing for a couple of months. Everyone is so tired of the shit we've been served up, and this just wasn't a big enough draw given the circumstances.
Those returning players deserved a higher attendance, and I think the club missed a massive open goal by failing to show any real acknowledgement of failings or promise to do better. Even something like that, or indication they're trying to do something would have rallied folks a little bit more. They didn't even try—they just banked on the anniversary as a marketing ploy. Very sad.
But anyway, as I said, I'm glad some of those who went (players included) had a good time.
