This is a server-side rendered catch-all page. It catches all requests made to /shows/:id/any/path/can/go/here... and makes those parameters available in getInitialProps():
[0]: 106
[1]: whatever
[2]: path
Refresh the page to see server-side rendering in action.
You can also try changing the URL to something random, such as /shows/106/whatever/path/you/want
