Addressing the topic directly, I would go as far as to day that Modern Orthodoxy really does not need to be ‘redeemed’ at all. In fact, I believe that without MO, less Jews would be engaged with Yiddishkeit and Judaism as a collective religion would be less accessible and vibrant to the idle Jew. I view Modern Orthodoxy as the real success story of 21st Century Judaism with active MO communities shining the Jewish light by making otherwise mundane and tamei social media and internet sites glorified, thus making the Jewish nation as a whole stronger and viewed in an increased positive light.
I would say that the only potential flaw with MO is the consequence of a non-cohesive MO community where communal leaders practicing Modern Orthodoxy inconsistently act as a destructive example to community members, as shown by the materialisation of the Partnership Minyan, for example, thereby leading a false Jewish life and in some cases braking Halacha.
However, this can be avoided and it is the responsibility of proud MO Jews to wave the flag properly and live a true life ‘Torah Im Derech Eretz’.
