Two weeks ago in Spain, the Mexican was highly critical of the 2014 season so far, saying it is "embarrassing" that GP2 cars are now rivalling F1 for laptime.
However, he expects drivers grappling with their high-torque turbo-powered cars between the armco at tight and twisty Monaco will be a spectacle.
"It will be really interesting here," Perez said in the Principality on Wednesday.
"We will see drivers make many mistakes. It will definitely be more exciting than in recent years," he is quoted by Germany's Auto Motor und Sport.
As per usual, Monaco rewards those with the highest level of commitment, prepared to brush the barriers for the reward of tenths.
The penalty for errors, however, is even higher, and Perez thinks that is doubly true for Monaco in 2014.
"An error here will cost you a hell of a lot," he said.
"There is no particular area where it is more difficult -- it is going to affect the whole track."
