I liked how they moulded the Penguin Character. I believe in batman comics, every person has 2 choices to do the right thing and to do the wrong. It's the choice which makes them the person who they are. That's how we have Batman and Joker. No one is evil from birth right away. So in the movie Penguin was insulted because of his physicality. That I loved. Taking time in setting up the villian's character. Sure I would love him coming back. But I guess already the TV Series Gotham has set him up perfectly. But you know more the merrier. I am up for another version of Penguin too, would be more interesting how anyone would set him up. I mean what would be the reason or motivation behind him being the Villian.
