I swear, if even ONE Gremlin is CGI...
I love the Gremlins films, but I know this is the best we'll ever get. Steven Spielberg himself has said he's ashamed of the films, calling them "too mean-spirited" (his words, not mine). I wonder what Spielberg thinks of Jaws, these days.
Since none of the talent wants to come back to do a third film, a straight to video sequel involving none of the cast (save for maybe Dick Miller and Corey Feldman...which would be awesome) is the best we're likely to get.
