I actually liked The Abyss, a lot.
As for True Lies, I mean it's stupid as all hell, but it's fun and entertaining.
I agree with Tore on Titanic, it's not my kind of movie, but I appreciate it as an extremely well made piece of filmmaking, it's an old fashioned tragic romance story, and I think for what it tried to be it succeeded.
IMO, his only bad film is this.
