"Dayya Dayya Dayya Re" was darn catchy, and it contains the excellent line "With your name on my lips, I spend my days. I spend my nights pining. I remember every moment the naughty things you did." The fortune teller from Lagaan makes an enjoyable, Bollywood-studded cameo. And there are only a few moments of wacky side characters.
There isn't much else of note here. It's not the worst movie I've seen, but there isn't anything to like about it particularly, and it isn't so bad that I have to rant and rave, and it isn't even intriguingly or enjoyably bad. There really isn't any point to watch it.
I generally like Aishwarya very much, but Tia didn't give her much to work with. And Arjun...well, he was boring. Paresh Rawal was by far the most enjoyable person in the movie. While I hadn't been led to expect much from this movie, I lost my patience towards the end, when Jai raises his hand to Tia and we never see him lower it, even after she flees the room. No. Not acceptable.
And, of course, the plot. The plot was pretty stupid, if not uniquely so (but think how much better this same idea was handled in Goodbye Lenin!), and I'm going to have to class it with Chori Chori Chupke Chupke under plots driven by bad, bad ideas. Gorilla's Lament pointed out that both have women in cowboy hats in them, and I think GL might really be on to something here. Observations by others on the correlation of these phenomena are very welcome.
