Inconsistent acting
I remember first seeing Freida in "Slumdog Millionaire" and being thoroughly unimpressed by her acting. Also, she had about 15 minutes total of screen time so I thought her performance and involvement in the film was overrated.
I then watched both "Miral" and "Trishna" and I was very impressed, especially with the former. I thought she did a great job. After that I watched a couple more of her movies, that were released AFTER those two, and her acting again was mediocre at best.
I wonder why she shines in a few films but is bland in most others. The two films where her acting was good were both independent films - maybe that has something to do with it?
