How bad is it? It could be the worst time travel film (and there are thousands of those).
Should you see it? Only in the MST3K version.
This film got brief publicity for being a film with Lisa Kudrow, but she was not in it (I don't see how anyone could confuse her for the actress she was thought to be). It was made for about $150000, lost money and then, when MST3K parodied it, it turned a profit... maybe that's a business plan. The plot is so hackneyed that, if you've seen one time travel film, you know exactly what happens. The effects are poor, the acting is poor, the script doesn't make a whole lot of sense and it doesn't stand up to watching without Mystery Science making fun of it.
