From "We're No Angels" where he was out acted by Sean Penn...

That's DeNiro's face in about seventy percent of his movies and scenes.
DeNiro is a good actor when he’s not doing the DeNiro stereotype (like Pacino doing the Pacino stereotype, and as for Pesci, well, we’re fine with the Pesci stereotype). “Godfather 2”, “The Untouchables”, “Angel Heart”, “Awakenings.” He is capable of good work. But, he’s done a lot of junk and fallen back on bad mannerisms (I thought, for example, the “Analyze This/That” was just execrable).
