“50/50,” directed by Jonathan Levine (known for “The Wackness” and “All the Boys Love Mandy Lane”), is a bittersweet story of a cancer-patient experiencing chemotherapy. The film is incredibly realistic and well maintains a comedic balance besides its difficult topic.

Inspired by a true story, “50/50”introduces 27-year-old Adam (Joseph Gordon-Levitt) diagnosed with a rare malignant spinal tumor. When he’s told his chances of surviving are 50-50, he is of course aghast, but his best pal Kyle (Seth Rogen) sees things differently.

“If you were a casino game,” he says, “you’d have the best odds.”

Known for roles in films as different as “Inception” and “(500) Days of Summer,” Gordon-Levitt is perfect like always in “50/50.” The actor ably conveys the heart sinking feeling of sitting on death row while still cracking jokes with his friends.

The entire cast of “50/50” is phenomenal and Rogan is no exception. His character looks at the glass half-full and uses his chemo-bald friend as a way to pick up girls. Rogan is laugh-out-loud funny and heart-rending at the same time.

“50/50” is flawless in every way from the authentic storyline and the dynamic cast to the beautiful soundtrack and wonderful directing.
