Why? Why did the writers think Prue getting stuck in a painting for 40 minutes would be entertaining? Shannen Doherty does her best with the material but... who cares? Even Phoebe getting a dose of smartness (for once) couldn't save this episode from being a complete disaster.
The Painted World has Prue getting stuck inside a painting which was delivered to Buckland's. Whilst in the painting, Prue realizes she is stuck inside with a warlock. When Piper also gets sucked in, Phoebe must save the day and using a Smart Spell in the Book of Shadows, manages to save her sisters.
This episode adds nothing to any ongoing storylines and Jenny continues her successful run of being the most annoyingly pointless character in Charmed history (well, until Billie pops up). This episode sees her asking for help with her sex ed class from Phoebe. If you need sex advice, just go to the resident neighborhood slut! At least Jenny did something intelligent for once!
Despite that, Phoebe is the best thing in the episode and the Smart Spell at least gives her something to do. Piper and Dan have some nice chemistry but I still can't get over the fact that Dan is completely devout of any personality. Stick with Leo!
This isn't a good episode at all and there's hardly anything redeeming about it. Instead of watching something about somebody getting stuck in a painting, why not just smash a painting over your head until you're in a coma, dreaming about more exciting things...
