I have the live action trilogy on Blu-Ray...and I think it comes with the SE for the first movie. The other two films....the second film might've made a decent "Outer Limits" episode. The third film....wow....the singing soldier really just made it stupidly cringeworthy. But the return of Rico (Casper Van Dien) was a halfway welcome appearance.
If only they could've gotten Denise Richards as Carmen Ibanez.
As such, despite owning all four movies, I only consider the first movie, and the CG movie "Invasion" as canon. (Sounds strange coming from someone who does not invest a lot of credence in which films are and are not canon...such as Star Trek or Star Wars
) Then again, I also consider only Superman, Superman II, and Superman Returns as canon in their series.
