So what if Taani didn't recognise Raj?

I didn't love this movie, but I'm frustrated at how most of the
negative reviews are focused on the wife not recognising her husband.
Have none of you seen Superman? In that, Lois Lane doesn't recognise
that Clark Kent is Superman, and yet I doubt any of you would complain
there. It is a trivial plot element that can be overlooked - and in the
film's defence, they did try and justify it by making romance a bit
magical (though probably didn't need to go that far).

The film was sweet, colourful, and fun to watch. The music was great
and the acting was decent. Having said that, I think there were some
fundamental flaws in the films and tricks they missed:

1. Why should the girl love Suri when he offers her none of the love
and fun that Raj does? I don't understand why she is supposed to settle
for the 'real' Suri when he is so boring. If Taani is supposed to
compromise for her husband, should he not also become a bit more like
Raj and meet her half way? It would have been great if he had started
dressing a bit more fashionably for her even in his 'Suri' self.

2. We are told that Taani is a loyal and decent wife. Yet it is
completely out of character for her to think about running away with
another man. I was a bit disappointed that she didn't even tell Raj she
was married and spent so much time with him outside home.

3. A perfect twist to the film would be for Taani to have known all
along - it would have been a nice way of showing that Taani did
recognise his heart from the start but she also wanted to see how far
Suri could go. But without this twist, the story was very predictable.

These things make the film very frustrating for me. But at the same
time, I don't want to fault it too much as I think it is still on the
right path - I'm fed up of the show-offy 'Don's of Bollywood today.
Romance is still where it's at.
