Yeah i fully agree with your point, and in fact being a massive complaintfest lover i get a little miffed when someone focuses on something like the hypothermia issue as it's not a stretch of the imagination to suspend disbelief for it, it belittles all the valid complaints like constant deus ex machina or in-your-face plot holes that you point out, and putting them together detracts from the important points, like the WW army not waiting for Jon to resurface and end what seems to be the NK's established biggest enemy (using Hardhome as evidence for that). For me the worst case of this has been how the White Walkers have chains in tow, people seem to off the map angry about it whereas I only really thought about it once it had been pointed out. That particular issue can be answered by many explanations and i'm not even that bothered if it isn't, it doesn't harm the story in any way. The battles are cool and everything, the dragon death and plummet below the ice was fucking jaw-droppingly brilliant, but as i'm watching i'm still laughing to myself at how ludicrous the whole thing is, which is a shame.
The Teleportation issues this season have ruined it for me the most but I can see how the casual viewer can turn off to them and enjoy the show. One of the best moments of the entire series for me is Stannis appearing at the last minute to crush the wildlings north of the wall, in both books and show it was entirely plausible and entirely out of the blue. To be able to pull off that kind of surprise and make it fit with the timeframe of the story is brilliant story telling. However now you just get the out of the blue, you don't get the plausibility that lends itself so well to the surprise, Euron turning up at 3 different places within a day of each other to crush entire armies completely negates the surprising moment it is, it's surprising because he was 3,000 miles away 10 minutes ago, and that's when, as a viewer, i'm thinking more of timelines when i should be watching and enjoying Euron kill off terribly written show characters, it takes me out of the moment, and it's too ridiculous to accept. It also makes the show so boring to know that they can just cut logic out at any moment for a cool set piece they have in mind.
It's largely down to the fact that the show was so well written for the first 3-4 seasons, they established laws within their own story that they can no longer follow on their own, and it's really distracting.
