Re: Overrated actors and actresses
It doesn't necessarily need to be a "realistic" movie for it to be believable and engaging. The aforementioned 'Imaginarium of Doctor Parnassus' isn't entirely realistic ether, but the lore and performances are captivating enough that it draws you in and makes you want to get lost in the world and suspend disbelief. David Lynch was a master at making dark, atmospheric movies that weren't realistic to mundane life, but the performances and direction still draw you in.
When I compared Bickle to Driver, I was just talking about the way they convincingly deliver their performances given similar character traits, that's pretty much where the comparisons stopped.
