These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternate Character Interpretation: Well - alternate show interpretation, really. Much like shows such as My Super Sweet Sixteen, it's not entirely clear whether the program was made to glorify the people it stars, or whether it keeps its tongue firmly in its cheek, casts a knowing glance at the audience and mouths, "Look how psychotic these folk are!"
The Viking Shores previews even had Nordic whalers angrily asking the crew "Who's going to feed this nation? You?" to point out that some of the whale hunting done is done for reasons people are more likely approve of—namely, feeding people.
Family-Unfriendly Aesop / Warped Aesop: This show seems to give the message that, instead of using diplomacy and enforcing regulations on whale hunting, having a hack team of environmentalists using violent and controversial means is more effective.
Refuge in Audacity: When the whalers hear about Watson's claim that their presence stops them from killing and processing whales, so what do they do? They do it right in front of them.
Rooting for the Empire: A somewhat literal case (given the fact that Japan is still technically an Empire), as you won't have to go long to find a few hundred pro-Japanese sites that are practically (and occasionally literally) screaming for the blood of those on the Steve Irwin. Even more with the Norse whalers since they are doing subsistence hunting, thus not in for profit, killing whales for Lulz, or even cold blooded research.
Snark Bait: Another interpretation of the show, attracting viewers amused by the crews' bungling.
Some Anvils Need to Be Dropped: though "eco-terrorism" is arguably not the best way of stopping it, whale poaching itself is a serious problem that menaces the very survival of several species.
One of the problems arises from the fact that the alleged poachers they are harassing either cannot and have not been proven to be poaching (int he case of the Japanese) or flatly are not (like the Norse), and that Watson has gone on the record excusing many actual cases of poaching (especially by indigenous locals).
