Keaton's portrayal of a psychopath was believable (although that "SULFURIC ACID!" was a bit forced), as was Garcia's sympathetic role. It's just you couldn't escape the anger you have for Conner for what he puts everybody through just to save his son. Multiple lives lost to save just one, not good math. It was intense, dramatic, but too many things threw it out of balance to make it anything special. And what's with Keaton exercising with sandbags at the start? Is that supposed to impress us?
