Ajay Devgn & Akshay Kumar both fully know the demand for content movies these days. Indian Cinema changes where audiences tastes often gets outdated and where they don't want to keep seeing the same thing over again. Both actors are versatile where they are much capable of doing different genres and roles.
Their work ethic is very good hence selective in choosing scripts but Ajay Devgn is more ambitious as he will often take time to work on project e.g. Tanhaji.
They've had their ups and downs but they more motivated hence these two have a fantastic lineup. I'm more excited for Ajay upcoming movies the most e.g. Bhuj: Pride of India, Maidaan, Chanakya, Kaithi remake, Singham 3 (TBA), Golmaal 5 (TBA) & Raid 2 (TBA)
Hope they continue their success but I'm more fond of Ajay Devgn as a fan. I really hope Singham 3 comes and gets announced in future. I'm dying to see this sequel happen.
