Tripped is a science-fiction and comedy TV show from Britain. The science-fiction fits squarely in the parallel universe subcategory, while the comedy fits squarely in the stoner subcategory.
Parallel universes was my main motivation for checking out the show. I've been a fan of such stories since watching Star Trek "Mirror Mirror" as a child and then later on with such shows as Sliders. On the other hand, I am just not into the stoner genre.
With that in mind, perhaps it is no surprise that I had mixed feelings about Tripped. I don't want to give any spoilers, but I actually liked the main plot behind the parallel universes. However, the stoner comedy alienated me entirely. It was a bit too slapstick and silly for my tastes.
Never-the-less, I still laughed out loud at a few moments and the underlying story is interesting, so I give it a slightly better than average rating. Fans of stoner comedy might get a bit more amusement out of the show. For something more serious, I recommend checking out the Netflix film and backdoor TV pilot called "Parallels".
