I remember going to see the first movie, I was mad that I didn't get the cards they offered, but w/e the movie was awesome...my mother slept through it though.
The second movie, I think I just waited for VHS to come out. The third movie I saw in theaters, got entei promo, and was happy (again, mother slept through hole thing...)
The other movies I either bought or rented from Blockbuster...I still like them even though I am older than the age limit nowadays
Lucario was the best movie I liked...
As for them being in movie theaters again, I think sure, PUSA could make some more money off of them in theaters, but kids on the poorer side of the economy wouldn't be able to see them unless it wasn't on television as well. I think Cartoon network has done good showing them on television giving those kids on the poor side of the economy a chance to watch them as well as the other fans w/o making the fans pay for it.
But I do miss those promos they gave away at the movies, even though I don't play the tcg anymore.
