The first movie was great, although it did suffer from mid-90s production quality. The CGI for Reptile, for instance, was terrible. Honestly, I think they blew their budget on making Sub-Zero's abilities look legit lol.
Annihilation, however, was a different beast. That was just terrible. Regardless, I need to go back and watch both of them lol
The sound track from those movies was, as the kids say these days, fire!
