I expect some people will pan this film completely, while some others who love B films will praise it to the extreme. I am not completely won over to either side, but overall, for a low budget comedy B Grade scifi horror, I have to admit it earns some noteworthy credit.
A lot of these kinds of films try SO hard to be funny and cheesy and they fail miserably. This one comes by both the cheese and the laughs honestly. It didn't exactly leave me with my sides splitting, but I felt entertained and at the end felt like I had been a part of a lighthearted cinematic romp, and at times some of the funny parts really hit well... and really what more can you expect?
Speaking on style and such, the acting is mostly quite solid, which is something many of these intentionally B films really fall flat on. The characters are quite flat, but of course they would be... it fits the genre. There are a couple times where the acting is off a bit unintentionally, but you have to let that slide and it is pretty minor overall. The humor is quite silly and juvenile, and a lot of it is drug centered (with fairly evident influences--most notably from That 70s Show)... but of course it is, THAT is usually part of the genre. The character effects and gore are extremely cheesy, with a straight up classic rubber suit alien who likes to pose dramatically to roar, and who teleports with cheesy little spark effects. Again... all exactly what one would want from a self aware B comedy scifi horror film. Sound is well done and lighting is handled professionally so you don't have to struggle to see or hear. The plot... well, I won't say much about it because there isn't much to say. It is what it is (although there is a bit of a ''twist'' to it).
All in all, honest entertainment for people who love the kind of movie it sets out to be. If it sounds like your kind of flick, then it probably is. I hope you watch it and have fun with it.
