I watched Men in Black 2 for the first time since seeing it in theatres last night, and some of the CGI wasn't so flash to watch today. Granted, it is often supposed to be cartoony - for example, Jeebs' regenerating head and Frank the pug, which were both still cool - but a lot of it was still quite poor. In particular, the main villain's CGI was bad, and the ship landing at the beginning was terrible.
Makes me wonder how MIB1 would fare nowadays, although I recall that being far less CGI-reliant (the main villain was completely make-up until the last scene, right?)
I also remember being appalled by Congo when I saw it (for the first time) about five years ago. If I'm right though, that came out around the time of Jurassic Park, and the SFX got quite a bit of criticism even at the time.
