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.
YMMV: Magical Record Lyrical Nanoha Force
YMMVs introduced by Force:
Contested Sequel: Largely because of the Darker and Edgier atmosphere, move away from Magical Girl tropes, new main character, and largely unsympathetic villains who defeat and severely wound Signum and Hayate. A good number of people have pointed to apparent lapses in the worldbuilding, raw writing and the artists difficulties with portraying dynamic fight scenes as a sign of a general drop in quality. Continuing questionable decisions and completely out of touch ideas of who the fanbase cares about seeing in a Hot Springs Episode mean the future is not bright, especially with the "temporary" cancellation.
Counterpart Comparison: A number of the Hückebein have been compared to the Wolkenwritter and other characters outside the franchise in trait similarities.
Crack Pairing: Signum/Cypha. It's almost exclusively based around Singnum being dominated and humiliated. It probably started as a thing to troll fans with, but since it became obvious that Signum would live through Force, it seems to have been jokingly accepted by the fandom, kind of like Mami and Charlotte.
Fridge Logic: Mariya uses live ammo in a fight against Bureau agents on the Mid—which is kind of a Big Deal, since live ammo is exactly the kind of mass-based weaponry the Bureau is supposed to crusade against. Yet nobody seems particularly interested in finding out where a lowlife crook like herself obtained such quantities of mass-based munitions in the heart of the Bureau's domain. Granted, she doesn't have an actual gun, but bullets usually come from the same sources as firearms...
In Chapter 20, Shamal asks Vivio if she wanted to join in the mock battle with Thoma and Signum. Why would she make that suggestion given how dangerous Thoma or Lily's Eclipse powers would be to Sacred Heart/Chris if Vivio tried to fight either of them? Nanoha, on the other hand, suggests Vivio to not get involved.
Hilarious In Hind Sight / Ascended Meme: Nanoha gets a new getup in this that actually makes her look like a Gundam bringing the "Nanoha is really a Gundam disguised as a magical girl" bit full circle.
Jerkass Woobie: The Hückebein may have been meant to be seen as this, but their attitude towards killing, lack of redeeming features and little emphasis on their plight prevents them from being sympathetic.
Jumping the Shark: Force is the season with the biggest amount of backlash to date. It elicited this reaction for having a heterosexual male lead and supposedly dropping the magical girl tropes. Not to mention they put some of the most cheered characters this franchise have in real danger of suffering Badass Decay, starting with Signum. There are also signs the author has guessed badly about how people will react to each new character they introduce, committing the same mistakes over and over and trying to shore them up in all the wrongways.
Thoma has drawn a lot of fire for being a very typical, male, angst-ridden main character with a Story Breaker Powerpulled out of nowhere that can beat out the established and well-developed main characters of previous seasons with little effort. His latest comments to both Signum and Cypha, where he wishes both the hero and the psychotic good luck and tells them to do their best before they fight, suggest Thoma has serious issues.
Cypha's caught a lot of flak for handing Signum her first real defeat, and for being kind of a bitch about it. When it was announced that Gears of Destiny will feature Force characters, many were hoping Cypha would be included, so they can beat the crap out of her.
Curren probably beat Precia's record for instant hatedom, considering the chapter with her first appearance wasn't even translated yet and people already wanted her to die. The reason? Debuting by instantly impaling Hayate in the back, just as she was finally about to do something awesome.
While he is mentioned in Replacement Scrappy, Thoma isn't liked for his behavior crossing into the What an Idiot territory and losing characterization into becoming what is seen as an idiot who keeps overlooking the behavior the Hückebein constantly exhibit. What's worse is that he is borderline useless in combat and is overshadowed by Isis and even Lily, combined with wasted character development potential.
Most people don't really like the AEC Equipment much. They prevent the heroes using magic a setting that has previously been about high-powered magic, they usually don't work, and anyone with a Strike Cannon rather than a personalized weapon gets taken down like they were a Mook regardless of what they were treated like in any previous version of Lyrical Nanoha.
Thoma became a fugitive from the TSAB by breaking into the lab, stealing the Divider, and escaping with Lily. This might have led to Subaru weighing her bond with Thoma against her duty to arrest him, as well as Thoma fleeing from the Bureau while having the Sympathetic P.O.V., but Thoma eventually loses control of himself to the Eclipse, and it becomes about having to try to get through to him, rather than him trying to protect Lily and escape the Bureau.
Force in general could have been presented straight as about the conflict between the refusal of most of the main characters to kill and the fact that the only solution to the Hückebein appears to be killing them.
Signum gets chopped up, and Vita gets taken out like she's a Mook, but they take it in stride. Which is more than slightly out of character. Every time someone has threatened Hayate's life previously, the Wolkenritter have treated them as mortal enemies. In Force, they don't seem to care nearly as much.
Unfortunate Implications: More than a few readers have noted that shoving a male lead character into the spotlight of a franchise focused largely on women, and then having established female characters lose repeatedly against male villains, is just full of issues (especially since two characters thought of by many readers to be a lesbian couple barely even appear). Slightly mitigated by how the male lead is a complete idiot who wouldn't be able to tie his shoes without his female allies holding the laces for him.
Viewer Gender Confusion: Until his profile came out, nearly everyone was convinced that Fortis was female. With his large eyes, dress-like robe, and feminine hairstyle, it's an easy mistake to make. Ironically, fortis can be translated from Latin as "manly".
If you have to name names... the Hückebein because of their anti-magic and other things. It overlaps with God-Mode Sue and even Jerk Sue. The villains are insanely powerful and the heroes have been forced to use forbidden technology to even have an effect on them in theory. In practice it doesn't work. However as of chapter 29 the veneer of invincibility is starting to crack.
Mostly thanks to Hades Vandein, who highjacks the role of Big Bad halfway through the story and makes the Hücks seem positively tolerable by comparison. Not only is he more powerful and somehow more smug, but he refuses to confront the heroes and makes them look like idiots when they can't catch him red handed, even though he's the most Obviously Evil guy ever.
