Nothing to do inbetween dungeons? I'm sick and bored at home, so let's compare!
OoT - Deku tree: find sword and buy shield
TP - Forest temple: spend 3 days in Ordon village, Hyrule Sewers, Get Sword and Shield, clear twilight.
OoT - Dodongo's cavern: Meet Malon, Meet zelda, Get Keaton Mask, Learn saria's song
TP - Goron Mines: Fix bridge, Clear twilight, Seize Epona, go back to Ordon village, Wrestle, Save Colin, Wrestle again.
Oot - Lord Jabu Jabu: Go to zora's domain, get bottle, return to zora's domain
TP - Lakebed Temple: Go trough twilight, find ilia, go to lake hylia, fly over zora's river, climb u to zora's throne hall, go back to death mountain, go back to zora domain to melt ice, clear twilight, go back to castle town, guide Telma and Ilia to Kakariko village, Get zora armor
OoT - Forest Temple: Get mastersword, get Hookshot, go trough Lost woods
Tp - Arbiters ground: Turn back into wolf, go trough larger hyrule sewers, meet zelda, go to faron woods, clear sacred grove, solve guardians puzzle, get master sword, Meet Telma, Go to lake hylia, Travel trough Gerudodessert/Bulbin Camp.
OoT - Fire Temple: Go to death mountain, get fire tunic

OoT - Shadow Temple: Learn song of storms, Bottom of thewell/get eye of truth
TP - Sky Temple: travel to kakariko, get ilia's memory back, go to hidden village, receive sky book, restore domion rod powers, Find missing Letters in Sky book, return to kakariko, go to lake hylia
OoT - Spirit Temple: Clear Gerudo Valley, travel trough haunted wastelands
TP - Palace of Twilight: Travel back to arbiters grounds
OoT - Ganons Castle: go to temple of time
TP - Hyrule Castle: Go to Hyrule Castle
So altough granted that they got a bit lazy, or uninspired perhaps, towards the end, overal you do a crapload more between temples then you did in
OoT. Which makes me wonder why on earth you feel like you do more in
OoT during the main quest. What I wrote down is pure facts, there's no way arround it.
As for sidequests and minigames, there's a decent amount in
TP:
Fishing
Zora river ride
Zora river flight
Goat herding
Snowpeak snowboarding
STAR game
Collecting Bugs
Collecting Poe's
Malo Mart
It's not that much less compared to
OoT, or
MM when you really think about it, it's just that the ones in
OoT and
MM we're more memorable, and a bit better in some cases.
I do agree on a lot of other things you said though, Why there isn't a path down to lake Hylia, God knows why. Same goes for why on earth they give you the horse reed at pretty much the end of the game. Towns aren't that bad, though it would have been much better if kakariko would become more populated along the main quest, and yeah, goron "city", Huge dissapointment. Castle town was good, but needed more houses you could enter.
Not liking the wolf gameplay or Midna, well, that's a personal opinion
So besides the things to do inbetween i mostly agree with you. I feel like they started out really well but got lost halfway the game. My main complaint would be that the world doesn't feel alive enough.
