Within the first few minutes we can see the less stellar caliber of acting and production. Nearly everything is made for ironic purpose, either it's intentional or not. There's so much exaggerated premise and clumsy delivery, it's hard to take the movie seriously and even as parody it can barely register any response, aside from a few chuckles when the film delivers terribly out of place scenes where you can't help but slightly grin.
The plot is a jumbled mix or time travel and a bunch of sci-fi gimmicks, none of these really fascinate. Actors are often cringe-worthy in their performance, although the lead may be funny since he looks adequately like a normal guy. Characters are variety of unsuitable personalities with jarring costume and hairdo, or just simply over the top misinterpretation of the era. Even it plays with historic and scientific backdrop, the film has no accuracy in either aspect. I guess it's a tad optimistic to hope for those.
It will get worse towards latter half, if one can make it pass an hour of characters waddling on a random field and tons of gibberish. The effect is abysmal, literal green screen mess. It has slightly lengthier runtime than most movies but there's really not much it has to offer. You might find some amusement, but it's recommended to invest time elsewhere.
