The plot was what it was. I won't talk about the plot. The majority of the film people were battling, but they were battle scenes where I felt confused by the stakes and actual to and fro of battle. A series of charges from sequentially introduced classes of monster, with no real geographic knowledge of where the battle lines lay and what was considered advancing or retreating by either side. There was Dale, but I felt like that went from Dale without orcs to Dale crawling with orcs from all sides instantly, without any reason to consider the physicality of Dale, how it is defended from as a fortress, what choke points can be exploited, what major routes of access have to be blocked, what is the absolute last line of retreat, where is cornered in and where will the final stand play out.
Its just a backdrop, not really an element of story so much as an alternative aesthetic. Whereas for me helm's deep is remembered as a historic solid place that accrued devastating damage in key dramatic stages of exponential significance to every character involved. The siege of helms deep was a battle scene where the placement of soldiers was telling of the narrative, who's holding down what, what has been lost, etc. And as the characters fell back through Helm's Deep this allowed for a real sense of 'just lasting through the night' in the a hope of a Pyrrhic victory because relief and rescue aren't counted on coming. As each new wave of troop or siege machine turned up, what it achieved outside of killing people was perhaps make it easier for future troops and siege weapons to kill people. Every successful demonstration of a ballista or berzerker or bomb meant something to the characters and their morale and exhausted them further on this long endless night. They weren't just exciting props dumped into a disorienting meat grinder like the five armies pit brawl.
I mean the orcs had dune worms. Nope, not gonna make the fact that the merciless villain could have released fucking dune worms and chose not to a point of insight into his psyche and code of honor. No no, my dune worms have shown off once for the cameras, I have no more use of dune worms. I guess the plot wouldn't have worked had the baddies tried their hardest. Their job is to just generally be everywhere and get slashed in passing as the good guys travel freely between landmarks.
