I saw both "Saving Aimee" and "First Date" at the 5th Avenue/ACT, and between the two, I personally enjoyed "First Date" more. I think it would have been moderately successful off-Broadway, but I do think this will tank rather quickly on Broadway at Broadway prices.
Though, if Eric Ankrim (one of the two leads) does make his Broadway debut, good for him. He's a pretty talented guy.
