While it's nice to see De Niro and Pacino in their third film together (but only the second one where they share screentime), the reunion is really disappointing. They are onscreen a lot together here, but the material just sucks. Maybe it's better to have them be in a movie together where they don't have much time with one another, but the material is far better. I think that's probably (and unfortunately) the best way to do it since it is both logistically and financially difficult to get either one of these guys to do a movie nowadays, let alone one together, especially where money is concerned. You'd think Hollywood would get that, but no. They care more about hype and selling tickets than producing something amazing. Thank God HEAT actually was a brilliant piece of work. In all honesty though, as great as it is to see them together, maybe it's just better to dream about such a thing happening, instead of it actually taking place (with the exception of HEAT).
Pacino and De Niro actually do give good perforances here, despite the material. How their performances rank compared to their respective filmographies leaves a lot to be desired, but overall, they've each given worse performances in other movies. The rest of the cast is kinda the same way. Not bad work, just mediocre stuff to work with.
I'm okay with plot twists, but the red herring here (and the big twist) really force you to suspend a lot of disbelief...moreso than I can buy really. I won't get into it, but I find it hard to believe that, aside from the red herring and the film's epilogue, that these two guys would solely be known by their nicknames. I think the main problems with why this film is a disappointment are the screenwriter and the director. Neither guy is all that good, Quality actors (and that includes the supporters, too) deserve better stuff and directors to guide them, especially in a film like this with so many notables.
If these Bobbay and Al ever do another film together, let's just hope it's better than this mess. I'm sure people thought lighteing would strike again by having these two team up again, but sadly, even the Earth barely moves, and that's a shame.
