Just watched the whole film series - I really thought I had seen the sequel before but it didn't seem familar. Catch the original when it cam out in the cinema but not seen it in a long time.
The first film is amazing - a great update on the Corman Monster films. One of the things that makes it great is the chemistry between the 2 leads (Fred Ward and Kevon Bacon) and you even get to care about all the secondary characters. Also the monsters are all models/puppets etc rather than CGI.
The sequels are all enjoyable but drop off in quality as they progress and they all feature less than stellar cgi effects. Kevin Bacon never reappears and Fred Ward once stars in number 2. From them on its the Michael Gross show. The 3rd sequel is interesting as it is infact a prequel set in the old west and starring the accestor of Burt Gummer who is a gun shy coward...
I am almost tempted to retry the TV show again.
