Believe it or not, I'd not seen Taxi Driver before last night. Maybe I was expecting too much but I didn't think much of it at all. Interesting in a 'film studies' kind of a way I guess but it's certainly not challenging my top 10 list.
I found the sax soundtrack hugely irritating, the dialogue at times to be inane, the acting almost pantomime (oh, yes I did!) and the story and pacing somewhat dull. That all said, de Niro's changing hairstyle was amusing (continuity not mohawk) and, on that continued hairy subject, I couldn't work out if Keitel's bouf was his own or a wig.
I ought say though, I'm not a fan of Scorsese as a rule but I (tried to) put that to one side. And I'm making allowances for it being dated and being somewhat of a student project. Even so, I can't agree with the laudits it gets.
