There are a couple of stabs directed at Star Wars (and one on Star Trek). But riffing on something popular does not make your movie really good. On the other hand, I don't think anyone will ever accuse the Sharknado movies of being intellectual or really something with gravitas (no pun intended of course).
There are quite a few cameos and star appearances (one from a fellow actor from another beast Scy-Fi movie with different animals as beasts. Btw. that other movie worked way better for many different reasons. So while CGI still is not anywhere near current tech, I don't reckon this will break the movie for you, if otherwise you liked it. It is really low and has me still wondering how there are still more of these to come ... Part 5 is confirmed for 2017
