Comparing the show to when H!PT had a subject they focused on with a few of them doing an activity it's pretty much the same. A bit more focused to geeky males with the educational focus on machinery etc and with the usual watching girls cook. But with their timeslot i guess they know who their audience is.
Fine i guess but i imagine the majority of foreign fans won't like it. But then the foreign fandom isn't big enough right now for them to try and impress us by making their programing interesting to foreigners.
