I think ACFC have a good side, but other than that it is dismal crap. Perhaps you only see the good side (your team dealing to other teams every weekend in an unevenly funded league must be pretty fun).
I get out and support it when I can, and enjoy watching football. But I'm under no illusions as to the quality. A lot of the Olympic Chatham cup games I managed to get out to were miles better and more exciting than any TW game I've been to. One central league game between Upper Hutt and Wellington united that ended 4-3 and meant WU were relegated stands out as a particular highlight.
I'd be much more interested in a team made up of all those best players from Wellington clubs, than watching whoever has ended up playing for TW this season.
