This ^^^
I've been going to Dons games for a long time and I didn't need ultras in any of the decades from the 70s onwards to make an "atmosphere" for me, if it was a good/great/fantastic game I'd be singing and cheering with the best of them, if t'was shite (an end of season 0-5 v Hearts springs to mind with Warner(?) in goal and Whyte in defence(?)) then I didn't want any of yer ultra's pish.
The displays are usually very good, but beyond that, meh.
