I have to admit I didn't like Jansen in the beginning, and then suddenly I started to like him. Now I think he's brilliant, even at the start of the game, it's strange. Guess he's just one of those characters who grow on you.
As for other good JRPGs (Warning, Long list incomming!)
PS2 - Tales of the Abyss(Enjoyed it more than Symphonia which was pretty hard to beat, funnily enough I can't play Symphonia now... =/),
Persona 3 & 4(Personally I prefered 3 over 4. Both were really good, but 4 was missing some depth with the characters I think.)
Suikoden V (It can get a bit slow at points, however I found the story very good, and I even went so far as to getting all the 108 stars of destiny, which is an achievement considering my short attention span)
SMT: Digital Devil Saga 1 & 2 (Excellent story, however it isn't for the weak willed, the dungeons are about 3hours long each and it can get pretty grindy )
Star Ocean Till the End of Time (Great game, same battle system as Tales of games, the added extra of creating items via item creation is awesome too)
Game Cube - Skies of Arcadia (Epic game, it's a port of the original dreamcast game, with added stuff. Definitely recommend it.)
Tales of Symphonia (Loved the game when I first played it, although I do admit now I can't play it after playing Tales of the Abyss, the straight line battle system is pretty tedious)
Baten Kaitos (Good game, a bit different due to using cards though)
DS - The World Ends With You (Excellent gameplay and story, kept me gripped until the end. I do admit the combat could get pretty annoying when your drawing a cricle, and it wont recognise it as a cricle...),
Final Fantasy IV (Great game and great story, definitely on par, or even better than the later FF's)
PSP - Crisis Core (If you liked FF7, I recommend it 100%, story is astounding, and at every point you feel for the characters(An achievement considering I hate Cloud and Sephiroth)
Tales of Eternia (Great game if you like the other tales of games)
X360 - Tales of Vesperia (Excellent game, thoroughly recommend it),
Infinite Undiscovery (Slow starter, however once you get into the game it becomes very fun to play, if you can withstand the annoyingness of the main character that is.),
The Last Remnant (Battle system is different, it's sort of like a small scale war, with you having 3 groups of allies, and the enemy having a couple of groups, I however thought that was a refreshing change. It's not for everyone though. Not sure if theres a demo on XBL, but if your PC is decent enough, you could try the PC demo to see whether you like the battle system).
Enchanted Arms (I thought the story was decent, the high encounter rate and annoying main character is enough to put some people off though)
Eternal Sonata (Great game and fun battle system, it could of done without the final chapter I do admit, but you can easily consider the boss at the end of the penultimate chapter the final boss, and ignore the final chapter if you wish, thats what I've done).
Blue Dragon (Iffy game, you either like it or you don't. I personally hated it, didn't like the immature main characters, or the, to me, generic story. That said, a lot of people liked the game. I think you'd like it if you liked the Dragon Quest series. I personally didn't like Dragon Quest either, so there you go).
That should be a big enough list to keep you going.
