You can think that it's alright but I need to ask you what was it that G1 got right that the movies got wrong, does it relate to character development, the narrative and story? You're asking for better writing but here's the question why do you like something why do you like the twist with the ark in BW, is it because of how it effects the plot and characters or because it tied back to G1? The answer to this question is very important regarding ones judgement of writing. It doesn't make sense because you won't let it make sense. Here's another explanation they take on the language and voice of the surrounding area wherever they arrive. Hotrod is in Europe during WWII who were one of the main allies France, It's likely Hotrod worked with a French army him having the accent of one of the main allies he likely worked with isn't far fetched. Dino landing in Italy and scanning their language and accent isn't far fetched. A robot taking on the voice and accent of whatever is in the surrounding area makes complete sense, why assume an English sounding voice if that's not the culture in the surrounding area. It makes sense if you think of anything beyond I don't like how they sound. Instead of looking for problems think of solutions. Why doesn't Sam use the shard to revive optimus, well look at where they are, he's a fugitive wanted by every government in the middle of nowhere with no idea where the heck Nest is nor does he have any means of getting there and if he did manage to find them he would be throwing himself to the people hunting him and would never reach optimus. It's not an option and it's suicide. Instead of looking for problems and claiming nothing makes sense, look for solutions and make sense of it. If you can't make sense of it no matter how hard you try then it becomes a problem.
