Renault boss Flavio Briatore believes changes brought in to make Formula One more of a spectacle have not worked.
Briatore has suggested having two races at each Grand Prix
"Normally it's boring," said the head of the current constructors' champions. "(The changes) have done nothing for the show."
Briatore would like to see two shorter races on a Sunday with the grid format changed to encourage overtaking.
"A one hour 30 minute race is too long because the last 30 minutes - 90% of the time - is really boring," he said.
"Every time there's excitement it's because something's happened outside or because it's heavy rain or there's some accident or stuff like that
"I still don't understand why we don't try to make excitement in every race."
People want to see people overtaking and fighting

The Italian would like to see two races - "one early in the morning and one later in the afternoon".
He expanded: "Maybe one race of 45 minutes and one race of one hour with a reverse grid in the second race like we do in GP2.
"People want to see people overtaking and fighting and if you put the quick drivers behind, the quick drivers will start overtaking, for sure.
"If not, the two cars quickest in qualifying are the two cars quickest in the race and win the race easily."
F1 chiefs have brought in a succession of changes over the past couple of seasons in the hope of making the sport more interesting.
They have included turning the qualifying session into a three-round knockout format.
But the 10 drivers who get through the first two stages must start the race with whatever fuel they had at the beginning of the final session, meaning drivers spend the first part of the final session burning off fuel before setting quick laps at the end.
"I'd have qualifying on Saturday maybe in a different way because nobody understands this (fuel) burning issue," said Briatore.
