  In this talk we will review the construction of M2-brane SCFT's highlighting
some novelties and the role of 3-algebras. Parts of our discussion will closely
follow parts of arXiv:1203.3546. Next we will discuss M5-branes: the basics,
the obstacles as well as various attempts to construct the associated SCFT and
potential relations between M2-branes and M5-branes.
