I agree. The earlier, lower-budget seasons of the show lead to some really clever solutions for testing things that would be unfeasible to try at full-scale. Now if they want to melt a semi truck with thermite they just buy one and do it. The target audience has really shifted.
My favorite part about the early mythbusters wasn't the science - it was the thrill of the build. To watch them having to build some weird thing, working through the possibilities, dealing with problems etc. Like the one where they tested if you could get electrocuted through an appliance in a lightning storm... they actually spent time troubleshooting the wiring in the house, and explained the problem. Now all you get is a 30 second montage before they start blowing crap up.
Absolutely! I hadn't heard it articulated as cleanly, but the "Thrill of the build" is exactly what attracted me to the show.
I enjoyed watching them try to come up with "How in the heck are we going to make this thing", along with calling car-lots, and the other stuff that they have the budget to avoid, or the producers do off-scene.
It reminded me a lot of Junkyard wars, when I first started watching it, but more authentic, since they weren't using a stocked field ;)
Stuck with Hackett still has a building things aesthetic, but it hasn't quite clicked with me.
