I played it as a kid on the N64, and I gotta say I enjoyed it. A lot.
It's not one of those games that you're going to be playing for hours on end or keep playing for months, but the game worked its Pokemon charm on me. The fact that you can now share photos only adds to the original experience.
I'd recommend it to any Pokemon fan
I think it pretty much only appeals to people who played it back in the day.
