The film itself is virtually B-movie in essence and doesn't hide the fact with crazy over the top acting and cheesy looking effects which at the same time do still kinda hold up today. The sequences where Aykroyd gets his teeth capped and the fight against the 'Rancor' type monster in the finale are fantastic examples of bad/good effects.
The whole film is that classic wacky genius you expect with Aykroyd and his unique thinking along with his amazing ability to reel off large segments of dialog without pause or fault. Other stars have a good time here too, especially Farley who strangely enough is the main love interest in the film and great little cameos from Sandler and Lovitz, nothing that hilarious but its funny.
Its such a silly, basic, childish plot and idea but its been so well directed and lovingly created with that good old fashioned SNL 80's originated comedy that it just can't fail to win.
The plot gets boring fast because you can only go with the chase and relocate plot for so long, while lots of stuff there doing is funny some is just to unrealistic and fantasy to even consider, and with such a great cast its sad that more could not come out of it.
I am not at all saying coneheads is a bad movie, but it was a movie made to quickly. It could of been much better had there been a little more time and thought put into it. It's worth a watch, but nothing spectacular.
