It's really hit or miss.
I really enjoyed the end credits to: Ghost Rider (first one), Hansel & Gretel: Witch Hunters, Taken (first one), Scream.
Then there were plenty I was absolutely disappointed with: Judge Dredd (Stallone version), probably most teen flicks, and most chick-flicks, especially teen-chick-flicks.
Game Of Thrones: Season 3: "The Bear and the Maiden Fair". :notgood:
Utter crap. Ruined season 3 entirely!
But made it up for with the Rains of Castamere. :love: Although that episode didn't have any pop/rock songs in the end credits.
There was an actual performance of "Rains of Castamere" by the group "The National" in season 2; episode 9: "Blackwater".
It was brilliant for end credits.
The Bayformers trilogy did alright with Linkin Park. I rather enjoyed their music. Especially the remix of Iridescent.
But after Linkin Park, they should have switched immediately to Steve Jablonsky's score and not other pop/rock songs. :notgood:
Tomorrow Never Dies had an excellent pop song by K.D. Lang "Surrender" which have made a better opening titles (as intended) and Sheryl Crow's "Tomorrow Never Dies" would have made a better end credits pop song.
The 2010 remake of A Nightmare On Elm Street did splendidly playing "All I Have To Do Is Dream" by the Everly Brothers.
On that note, the FX original series "American Horror Story" had a number of great pop/rock songs for end credits.
The biggest hit was "Baby, You Ain't Looking Right" by Powersolo. Which was used in True Blood prior to AHS.
And probably every TV show that was made in the 21[sp]st[/sup] century.
It was great whenever AHS used any old song that sounds like it came off a phonorecord.
True Blood had a huge hit/miss ratio. There were plenty of times I would just end the episode before listening to the rest of the end credits while other times I just let it play out.
Quintin Tarantino has a tendency to do well.
His earlier years were much more pleasing. Way more pleasing.
He's converted entirely to depending on Morricone for EVERY THING he does.
I don't mind it. It broadens my horizon to new music and new genres as I don't normally listen to pop/rock so much at all.
I can name a few rock bands/artists that I like but can't name their entire history, life experiences, drugs they've used, hookers they slept with and every project they did.
I won't say I "like" it as that usually leads towards people thinking I know everything and anything about what I "like" when I really mean "I didn't turn it off so I could listen to the rest of the end credits".
It's my window to the "modern" world that isn't score.

Morgan Freeman narrating: "That's classical to you.
I wouldn't have minded if the end credits to Shawshank Redemption was "If I Didn't Care" by The Ink Spots.
