“After the third season, it seems that they settled into finding things to blow up.”
And this is a problem... how?
More seriously, they also shot at things (probably my favorite part), and built stuff. At this point their main fan base is people who enjoy watching them kibbitzing together, and the trio was much better at that than Jamie and Adam.
The SHOW’S main fan base, that is.
Some one with some smarts should grab these three and build a show around them.
