I give this film an 8.0/10. The plot is a bit slow (it took about 45 minutes to an hour to begin to comprehend the story) but the quality of the actors make up for the shortcomings in the script.
It's 1998. Hank (Austin Butler) is a bartender in NYC and he struggles with memories with a car crash that killed his friend and ended his promising baseball career. Russ (Matt Smith), a British punk rock neighbor, is visiting the UK and asks him to watch his cat Bud (
Tonic the Cat). While looking for Russ, who was supposed to have returned to pick up Bud, Hank gets caught up in Russ' drug dealing operation involving Russian mobsters, Hasidic crime bosses, and a corrupt NYPD detective (Regina King). Hank has to find a way to get out of this situation alive.
What's good/great:
1) Tonic the Cat. EVERYTHING he did was FABLULOUS!

2) It appears that Austin Butler did all (or at least most) of his stunts. Which got INSANE.
What's MEH:
1) The use of the San Francisco Giants as a plot device just got boring after awhile.
2) I didn't like that it took so long to understand the ENTIRE situation that Hank found himself in.
3) As awesome as Tonic

was, I don't think a cat should have the most coherent parts of the script.
