I don't always like to nitpick... but when I do, I like to nitpick things I watch
Like I said... not a huge deal to me... but something I can't help but notice. As we've debated many times in many show threads... suspension of belief is necessary to accept some aspects of a fantasy program... but when they purport to set the show in a realistic world... then you expect that world to follow the rules that have been laid out.
IF they suddenly can make those uber-bullets without any effort (i.e. it all happens off-screen and they never run out again like they did in the finale)... then it loses meaning. It's like the jamming thing. Over the hiatus, somebody realized that the ability to jam those mechs like that was too powerful a tool and they either would have less threat this season because of the jamming OR they had to move forward.
So... they chose to move forward with a throwaway "they learned to overcome our jamming signal" but they also similarly glossed over how long it took them to make a handful of bullets... so they got rid of one too-easy plot device (the jamming) but kept the other (magic bullets) and now apparently those bullets are so easy to make that they can make them while on the run and firing dozens a second... and not run out except for the rocket.
It doesn't make me not watch the show... but it does make it less believable within the world they created.
