I rank them in order
Friday is a bonafide classic. The best one in the series and not really debatable. It had so many legenda in it and introduced us to many of them.
Next Friday had to live up to expectations, and with Chris Tucker bouncing alot of people were doubting. But they delivered another classic. Introduced us to Mike Epps who kinda became the go to sidekick for Cube. And it had fine ass Karla in it.
I've only seen the 3rd one once. I remember it being funny...but not anywhere close to the first 2 or even All About The Banjamins.
