The wedding was not a “royal wedding,” there was no feasting with 77 courses, there was no singing with 7 singers, there were no pyromancers conjuring shapes out of flame, there were no dancers, sword swallowers, jugglers, etc. The royal wedding was a festival, it was gay, it was pretty much a circus. Instead we were bored with just watching one table where people sat like statues, and people occasionally recited lines.

No one mention this was the 300th year of Aegon’s Landing and thus it was implied a new glorious dynasty was being forged due to the anniversary.

Tyrion was not a drunken sot.

The dwarfs with the five kings didn’t feel right, I understood why they had to cut the dog and the pig, but it didn’t feel right.
They used the wrong wine cup, it was supposed to be the two foot tall goblet that Mace Tyrell gave Joffrey.

The wedding just felt off. SPOILERS select to see (pretty much the wedding felt more like Tommen’s Wedding instead of Joffrey’s Wedding)

We get stupid things that either waste your time (Cersei ordering Pycelle to throw the food to the dogs), or does not make sense (Loras eyefucking Oberyn, “When the sun has set no candle will replace it.”) Things just didn’t feel right, Brienne introducing herself once again to Margarery and not doing anything about Sansa. The kingsguard member (Meryn Trent?) just standing against the wall while Joffrey choked.

I could go on and on, but I rather not. The wedding just felt like a let down, this was one of the best scenes of the book, but it felt completely different when they filmed it on tv due to director decisions (similar to the House of the Undying.)
