Liam is really annoying to me, the rest of the cast seem ok for now. The second reward challenge and the immunity were pretty good and not that obviously low budget. I wish they'd had a bit more strategy talk in the edit leading to tribal, but otherwise the edit seemed ok and covered quite a few. No time for sob stories which can waste edit time like in the latest US season.
The highlight for me may have been the exploding rocks, that's the funniest thing I've seen on Survivor for a while.
Water is an essential, there's no way people would go without it. They don't even have coconuts to drink from there. And flint is always given to the losing tribe at the first tribal, so that's not an issue for more than a couple of days. There's no way they could allow water issues at all even for that long though. I think there may have been wells/water containers on some Survivors before, the drier the location and the fewer fruit/vegetable water sources the more necessary possibly.
