Through three movies, the characters of Harold and Kumar have proven themselves to be the drug-fueled, spiritual heirs of Cheech & Chong.

As such, viewers need to self-select for “A Very Harold & Kumar 3D Christmas,” a lewd, funny and occasionally sacrilegious trip through the holiday season.

Harold (John Cho) has cut off contact with his old buddy, Kumar (Kal Penn). A mysterious package addressed to Harold arrives at Kumar’s door, and that sets the reunion in motion.

Harold’s scary father-in-law (Danny Trejo) brought a special Christmas tree to the family celebration, and it’s a charred mess minutes after Kumar arrives at Harold’s door.

The rest of the movie follows Harold and Kumar’s search for a replacement tree. It’s a wild night that includes run-ins with Russian gangsters, Santa Claus and Neil Patrick Harris.

As he does in “Harold & Kumar Go to White Castle” and “Harold & Kumar Escape from Guantanamo Bay,” Harris plays an evil version of himself who still comes off as likable. Quite a trick.

Some won’t appreciate the way Jesus is depicted in a scene in heaven. Others will have problems with a running gag about a toddler who keeps getting exposed to different types of drugs. There’s also full-frontal nudity.

“A Very Harold & Kumar 3D Christmas” isn’t a great movie, but it is a funny one, even if some of the laughs make you feel queasy.

It also should be noted that the filmmakers have fun with 3D. So many other movies use 3D to add depth, but I enjoyed the way “Harold & Kumar” shoves, shoots and pushes old fashioned, gimmicky effects at the audience.

I give “A Very Harold & Kumar 3D Christmas” a B minus.

It’s showing at Malcos in Tupelo, Oxford and Columbus, and Hollywood Premier Cinemas in Starkville.

Look for movie reviews in Scene on Thursdays, and listen each Tuesday morning on Wizard 106.7 between 8:30 and 8:45 a.m.
