When I define "shipping" it is the plan to have two characters get together (marriage, proclamation of love etc.).
Why do I hate it so much? I think it derails tv shows. It takes a show off its path and forces the audience to focus on the shipping and not the show.
I watch a show and think wow those 2 are great together but realize that it can't happen because the commandment of shipping will not allow it. Here are some examples.
Ephram and Lainey (Everwood) great together. Sorry he has to be with Amy who is horrible to him.
Josh and Amy (West Wing) great together, loads of chemistry. Nope Donna.
Lip and Mandy (Shameless) it worked! Lip and Tami yawn.
Stevie and David (Schitt's Creek) so much chemistry, so great. Patrick, sorry no, just no.
Otto (Sex Education) and anyone else besides Maeve. Worst shipping in history.
Friends-Best shipping and chemistry was Joey and Chandler. The rest was horrid (honorable mention to Monica and Richard, Brad Pitt and Phoebe)
