Kilmarnock manager Kenny Shiels felt his team lacked an entertainment factor but showed battling qualities to beat Hearts 1-0 at Tynecastle.
The manager's son Dean scored the only goal of the game from the penalty spot in the second half, with Hearts having had Ian Black sent off in the first.
"It's the second time this season we haven't entertained our supporters," said Shiels.
"We showed a different side to us where we dug in."
Black saw red after a late lunge on eventual matchwinner Shiels with Marius Zaliukas felling Paul Heffernan for Killie's spot-kick.
"The boy's a great player, Ian Black, and he doesn't need that in his game," said Shiels.
"Hearts are the most aggressive team in the league, that's the way they are and I'm not saying that in a critical way but that's just the way they play.
"I can't be critical of the boy because I didn't actually get a good view of it. But what I would say is if it was a silly challenge then he deserved to go if the referee judged it as that.
"He [Heffernan] looked as though as he was homing in on goal. It looked an obvious penalty for me.
"I thought the player [Zaliukas] would've seen red but we've been really below standard today in comparison to how we've played.
"We can't revert back to the type of football that was of yesteryear.
"We got a result but I have the same feeling now as when we lost to St Mirren and lost to St Johnstone, when we played really well.
"We got a bit of luck today for a change. It wasn't like a quality passing performance that we normally give so I'm disappointed from that perspective because you always want to have utopia.
"You want to win and entertain and today we won so I'm pleased for the supporters that we got the result."
