If we want to compare shitty movies I'm sure Deniro takes the cake in sheer quantity of garbage churned out. If you want to compare the two that's also interesting considering Deniro has played himself in every successful movie...where MM does show some range.
And if you actually hate his character in Dazed... then I doubt you even know what movie you're watching because he has the best quotes in movies history there:http://youtu.be/Xqy62kBAiLk
He plays the perfect guy hanging onto the easy life, ready to fade into obscurity.
Contact was a great movie despite it's flaws. I thought it dealt with advancing technology nicely in a continually complex political climate. Tough shit they didn't show her landing on a alien homeworld. That's not what it's about.
When an actor has been in the business for decades it's easy to pull out shitty movies, even the greats make duds. But you're ignoring his good movies.
Frailty was amazing. One of the freakiest movies I've seen.
A Time to Kill was great
he was legendary in True Detective
I haven't seen Mud but that looks interesting and it's in my queue.
and Dallas Buyers Club was highly regarded as well.
