I didn't like Badla that much. Something was missing. Evaru is one of the very few movies which managed to be better than the original movie. The truth is I completely forgot about Badla because it wasn't that memorable movie for me. I only got to know that it's the remake after I watched Evaru. I haven't watched The Invisible Guest though. The only problem I felt with Evaru is that some camera angles were set so that we can see Reginna Cassandra's cleavage. Well, that's understandable cause the makers might have thought at least that will bring audience into the theaters. There are a few plot holes here and there. But Evaru is an awesome thriller.
