"Desperate Measures" suffers from having an illogical and, frankly, impossible plot. The villain is akin to a cartoon character while the bank manager and police officer are little different. That said, the principal characters do their best with what they've been given - ridiculous plot, a plethora of unlikely circumstances, and a fairly mundane script.
A less likely gang of bank robbers is not just hard to imagine, it's impossible to imagine. How a nervous bank cashier is transformed into their leader is a question better not even asked. However, if all of the impossibilities and other failings are put to one side, the series can be watched and even enjoyed. The story does move along at a decent pace and is interesting despite being so implausible. Rather oddly, I found myself reasonably gripped despite its deficiencies, and award it a 5, which somewhat surprises me.
