'Wall Street' makes for an interesting watch, anything to do with the titular financial market is total gobbledygook to me but even I was fairly hooked throughout. The performances of Michael Douglas and Charlie Sheen are top notch, so no surprise it turns out to be very good.
I would say that the pacing is not the best, it probably overstays its welcome a bit, though to be honest that's the only thing I have to list under negatives and it's not even a big one. The relatively more energetic ending does do a fair bit to quell any serious run time issues.
