Those bombers, those stupid effing bombers
They have got to be the stupidest plot device in any sci-fantasy movie ever, and their ineffectiveness is matched by the incompetency of the pilots involved. They are easy targets for the First Order to pick off, and they fly in such close formation that chain reactions occur. Perhaps their bombs are extremely powerful, but that's more reason to keep them apart, and what's more, where are the fighter escorts for them? And where are their shields? If the main Resistance cruiser can have powerful shields, why can't they? And don't get me started on the unnecessarily complicated way of launching the bombs by electromagnetic propulsion.
I think it would've been better if they were missile launchers, firing off thousands of them and becoming armed shortly before hitting the target, and what's more, have them leave trails, too. Those scenes in Battlestar Galactica were so cool, they should've done it here. Minimal risk to the ships and pilots, and the target will still blow up.
No, the ultimate aim of those ships were as a plot device to introduce us to Rose and her sister. It's such a shame we never got to know the more capable sister, you know, the one who actually saved the Resistance and heroically gave her life, and not Rose, who wasted valuable time and ultimately threatened the Resistance by preventing Finn from heroically giving HIS life for the cause. Then again, I have to wonder what would Rose's sister have done if that control pad had never fallen down?
