One Direction and the Beatles don't have anything common other than strong studio production. Sonically 1D is rooted more in synth-pop of the 1980s, only acutely refined and commercialized, while the Beatles emerged from the beat movement and were influenced by folk, and later even eastern culture. Also Lennon's solo material (+ material with Yoko) was politically charged. Them being the most popular pop groups of their decade is very shallow grounds for comparison.
