I think it's cool to see various depictions of the Last Supper, because it was definitely a defining moment in Christian history.  I think its interesting to note that the intention for the work was strictly tourism.

I agree that it should be preserved for future generations, because it calls for comparisons between other Last Suppers that also calls attention toward the innovative artwork of Tintoretto's time. 

Along with other pieces of the Last Supper, what are some of his other works?
