Gary O'Neil said video assistant referee decisions are getting ridiculous after his side were beaten by West Ham.
Kurt Zouma scored the first goal despite the ball hitting the hand of Hammers' defender Thilo Kehrer.
Said Benrahma converted the Penalty late on.
There have been 10 serious VAR checks since O'Neil arrived.
The Cherries boss was booked for remonstrating with the officials after Zouma's goal after he felt his side should have been awarded a penalty.
The ball hit Kehrer's hands when he tried to head it from a corner in the 45th minute.
The ball glanced off the heads of Flynn Downes and Kurt Zouma before hitting the Bournemouth keeper.
The goal was allowed to stand despite the fact that it wasn't a goal.

The defender's arms were judged to have been in an unnatural position by the VAR, which led to the penalty being awarded for the second time.
O'Neil said he thought a foul could have been committed before the ball was thrown. It was a cute one, but we were docked points for Jefferson Lerma's foul on a teammate.
Zouma's goal is questionable. He moved his hand toward the ball. I am not surprised because it is getting ridiculous.
The referees have three important considerations when making a decision.
There was a mistake in the build-up to the goal.
Sean Dyche and Jamie Carragher were both of the opinion that Zouma's goal was correct, but the West Ham boss said he had not seen the incident again.
The handball law is an utter mess, according to Alan Shearer.
O'Neil wasn't happy with West Ham's second goal as a VAR check gave them a penalty after the ball hit the arm of the defender.
After the game, the Cherries boss spoke to the referee about the incident, and he thought it was different.
O'Neil disagreed with the man who said the arm was unnatural.
His arms were going back down when he slid in. He isn't trying to get an advantage. Things are going against us.
He said that his arm was in a natural position. I don't agree. They both moved to the ball. We didn't get as well as the one Ben Johnson handled.
