I think Aadesh was good in BVD but in that serial, his character was a supporting role and it suited him as the character didn't have too many range of emotions. So he was fine in BVD. But here he is supposed to be playing a lead character but he doesn't have screen presence, which is very important for any actor who does a "lead" role. He simply doesn't seem like a "Lead" or "Hero" material. Take for example yesterday's fight scenes, they gave him hero's entry, BG music and all, but he was no able to create any impact on the viewers at all. That is the main problem here along with that there will be comparison to the previous lead actor, which is also inevitable.
Even many actors who are excellent as actors, are not always hero or lead material and there are many examples for this. When they do such a lead role, even they fail. So the actors should choose the roles, which they can do justice to, keeping in mind their strength and weaknesses. Otherwise they will have to face criticism.
