We know there’s always a bunch of FRONTLINE films you meant to see, but somehow missed. Where to start catching up?

We went back through our archives to find the five films that resonated most with viewers this season. We looked at why you watched, what you liked and what you said about them. We’ll post one film every day this week — in no particular order.

Our first pick was Raising Adam Lanza. Our second was The Retirement Gamble. No. 3 was Life and Death in Assisted Living. Here’s No. 4:

The Untouchables

In a little less than a month, it will have been five years since the start of the global financial crisis. But as FRONTLINE reported in The Untouchables, nearly half a decade later, there have been no criminal prosecutions of any banks or senior Wall Street executives related to the sale of bad mortgages.

That struck a chord with many FRONTLINE viewers.

“This is one of the most important news stories in the past 5 years,” tweeted one viewer, Jose A. Villalobos. “@frontlinepbs again gives light to a subject being pushed into the dark,” tweeted viewer Mark Summerville.

If you missed The Untouchables, the full film is available below.
