Sorry I overlooked the question, I was born in 1987. I recall I first caught TLC on the USA network probably around 1995 or 1996.
Regarding the dog's name being Indiana, I said it's not something I have an issue with, it just seems a little strange that the family dog is where he would've gotten his name that people know him by, although it's not totally senseless since I can see him being attached to the dog and he could've taken the name as a means of honoring him.
And actually my reasons for finding TLC to be an inferior film to the rest doesn't have much to do with Henry, Sr. at all, I even said I really like his character. I just felt he had some goofy moments his character would've been better without. I wasn't expecting him to be a total copy of Indy and didn't even want him to be, I just expected him to be a more serious and stern character. Hope this clarifies everything. I probably should've just been a bit more detailed and thorough.
My reasons for finding TLC to be weaker than the rest for me among a few things is yes, it was definitely a Raiders retread in so many ways. After how well TOD showed Indy can work without Nazis and a different mythology, the film going back to retreading Raiders and with a much lighter and sillier tone was definitely disappointing. I generally don't have problems with sequels that are overly similar to the originals so long as they at least vary things up enough that they still feel fresh enough, but I think TLC much of the time was far too much of a mirror image of Raiders.
Other problems I have with it is that is also lacks the feeling of danger and peril ROTLA and TOD both have in spades that helps to make them that much more exciting and thrilling, a lot of the humorous moments are silly and take me out of the film sometimes, the villains are the least interesting and least menacing of the series, the climax is somewhat disappointing and I think the way it reduced Brody to a bumbling cartoon character was totally unnecessary. The way a lot of people tend to feel about Willie, Short Round and Mutt is very much applicable to how I feel about TLC's version of Brody and for some reason, Elsa is also a character I never liked and always found annoying and unlikeable, even though she's not a screaming and whining type like Willie. And as I also said, I really dislike the revelation how Indy stole his look from the explorer at the beginning. It just cheapens his character to me, to think his famous look with the fedora and jacket was something he stole from someone else.
I still love the film, it's fun and I always have a good time watching it, but of the original trilogy it definitely holds up the least well IMO, and overtime I've grown to enjoy KOTCS slightly more as I like that Indy at times feels more like his proper ROTLA/TOD self, the overall tone isn't as comical and the storyline was more creative and interesting to me. It has silly moments in it that are jarring yes, such as the fridge and swinging monkeys, and I won't argue or deny it's other flaws, but overtime it just feels like a tad more satisfying to watch than TLC these days.
